The HUAWEI ban explained: A complete timeline and everything you need to know

If you’ve been following the tech industry over the past few years, you no doubt know that HUAWEI is in a heap of trouble. Since May 2019, the Chinese company has been under fire from the United States government, resulting in what is colloquially referred to as the “HUAWEI ban.” This ongoing battle has forced HUAWEI to change its business practices drastically. Subsequently, the company now has no ability to keep its products on the list of the best Android phones you can buy.

If you are curious about how the HUAWEI-US ban came to be, the details surrounding it, and what it means for HUAWEI going forward, this is the place to be.

Below, you’ll find all the integral info related to the ban. We’ve also got some helpful tips related explicitly to HUAWEI’s smartphones and how the ban affects current and future handsets.

Editor’s note: This HUAWEI ban summary is current as of November 2023. Since this is an ongoing situation, we will regularly update it with new content. However, we advise you to check our latest HUAWEI news articles for the most up-to-date info on HUAWEI.

Why is HUAWEI banned? A (very) quick summary

Although this article is an in-depth examination of the HUAWEI ban, you might be happy with a shortened version of the story. The basic gist is as follows:

With the HUAWEI-US ban in effect, the company has had to completely revamp how it creates and releases smartphones. It also faces mounting scrutiny from other nations, many of which rely on HUAWEI for wireless networking equipment.

Since May 2019, HUAWEI has had some minor wins, but the bulk of the ban is still in place. It appears the HUAWEI ban will be in effect in perpetuity, and the company will need to strategize around it until further notice.

Yes, despite Donald Trump’s exit from the White House, the HUAWEI ban remains in effect. We will have to wait and see if it is repealed in the future — though it seems unlikely.

The HUAWEI ban went into effect on May 15, 2019, as part of an executive order from then-president Donald Trump. The order banned the use of telecommunications equipment from foreign firms that are deemed national security risks.

No. Although Donald Trump is no longer president, his executive order remains in effect. HUAWEI is still releasing flagship devices in Europe and Asia, but they are still not available in the United States.

It does not appear as though the US has any plans to end the HUAWEI ban at this time. According to Reuters, President Biden signed the Secure Equipment Act in November 2021, which prevents companies from receiving equipment licenses from US regulators.

No, the HUAWEI ban only affects products released after May 15, 2019. The HUAWEI P30 Pro launched on March 26, 2019, which means it can still feature Google apps.

HUAWEI history: The background info you need

In the grand scheme of things, HUAWEI is a relatively young company. Ren Zhengfei started HUAWEI in 1987 after being discharged from China’s People’s Liberation Army. Zhengfei’s military history helped HUAWEI get some of its first big contracts. This is one of the main reasons HUAWEI is viewed as a de facto branch of the Chinese government.

HUAWEI has faced scrutiny from the beginning for allegedly stealing intellectual property. In brief, the company would be repeatedly accused of stealing technology from other companies over the decades and then passing it off as its own. There are a few times in which this has been proven, such as with a 2003 case filed by Cisco, but there are many other times where accusations didn’t lead to confirmation.

In the late 2000s, HUAWEI was growing at an incredibly fast pace. The company started acquiring other companies to expand its operations. It attempted to buy non-Chinese companies several times, and regulatory bodies would block the sale. This happened in the US and the UK, among other areas. Each time, the reasoning behind the block would be related to HUAWEI’s deep ties to China and the possible security threat that it represents.

Eventually, HUAWEI started making smartphones. Its phones became popular immediately as they were well-designed devices with very reasonable price tags. In 2016, HUAWEI boasted it would be the world’s largest smartphone manufacturer within five years. By 2018, it had taken second place ahead of Apple and just behind Samsung. This is a remarkable feat, considering HUAWEI was handicapped by not having any presence in the United States, now the world’s third-largest market.

Donald Trump, China, and the ongoing trade war

While HUAWEI was growing at an astounding rate in 2018, all was not well regarding its home country. Donald Trump started to flex his power as POTUS to combat China and its “unfair trade practices,” as he called them. This began the still-ongoing US/China trade war.

Although the trade war has much to do with politics, tariffs, and international law, it also touches on intellectual property theft. Since HUAWEI has a reputation as a repeat offender regarding IP theft, this put the company in Trump’s crosshairs.

A major aspect of the US/China trade war is IP theft, something that has dogged HUAWEI's reputation for decades.

However, critics at the time noted that a long-term US/China trade war would hurt both countries significantly. Because of this, it was assumed that Trump would try to strongarm deals from China that would be advantageous to the US and then be done with it. This isn’t how things went, though.

Even though the trade war is associated very closely with Donald Trump, it is actually one of the few moves he made during his presidency with bipartisan support. Current US President Joe Biden has made no efforts to remove the HUAWEI ban or weaken the US/China trade war. Members of his staff and the people he appointed have also signaled support for continuing the ban.

In other words, HUAWEI isn’t out of the woods even with Trump out of the White House.

The HUAWEI ban begins on May 15, 2019

On May 15, 2019, President Trump issued an executive order that bans the use of telecommunications equipment from foreign firms deemed a national security risk. The order itself doesn’t mention HUAWEI (or even China) specifically. However, the US Department of Commerce created what it refers to as an “Entity List” related to the order that does contain HUAWEI’s name.

Since the order didn’t reference HUAWEI specifically, its effect on the company and its various lines of business wasn’t obvious. It appeared the order was primarily directed towards HUAWEI’s telecom operations, which would mean its wireless networking equipment, especially those related to 5G.

Trump's executive order for the HUAWEI ban left out many crucial details.

The order also didn’t make it clear whether the US government would help carriers pay for removing HUAWEI equipment. It also didn’t clarify any punishments US companies would face if they didn’t comply with the order. In brief, the HUAWEI ban seemed serious, but there were too many unknowns to understand where it would go.

HUAWEI, in a statement to Android Authority that day, said this: “Restricting HUAWEI from doing business in the US will not make the US more secure or stronger; instead, this will only serve to limit the US to inferior yet more expensive alternatives, leaving the US lagging behind in 5G deployment.” Even this statement made it seem like Trump’s order would only apply to HUAWEI’s networking gear and not its smartphones or other products.

That all changed a few days later.

Goodbye Google: The HUAWEI Google ban, explained

On Sunday, May 19, 2019, Google publicly declared that it would comply with Trump’s HUAWEI ban. Interpreting the language of the order, Google determined that the proper course of action would be to cut HUAWEI off from Google’s suite of digital products.

This meant that HUAWEI would no longer have access to the fundamentals of Android smartphones. Gmail, YouTube, Google Drive, and even the Google Play Store itself were now no longer available for HUAWEI to use on new products.

This news sent a shockwave through the tech world. Remember that at this point, HUAWEI is the second-largest smartphone manufacturer globally, and every single one of its phones runs on Android. Without access to Google apps, millions of HUAWEI smartphone owners were understandably concerned that their phones would suddenly stop working correctly.

When the dust settled, it became clear that HUAWEI phones certified by Google and launched before May 15, 2019, would continue to operate as usual. However, any uncertified phones, tablets, or other products released by HUAWEI after that date would be Google-less.

Not long after Google made its announcement, other US-based companies followed suit. This included Qualcomm, Intel, ARM, Microsoft, and many more.

HUAWEI tries to fight back

Bogdan Petrovan / Android Authority

HUAWEI wasn’t about to take this lying down. Only a few days after the HUAWEI-US ban took effect, the company issued several sternly worded statements declaring its intentions to fight the order. By the end of May, the company had filed a legal motion declaring the ban unconstitutional. Towards the end of June 2019, HUAWEI filed a lawsuit against the US Department of Commerce over the Entity List.

Unfortunately, these legal maneuvers didn’t bear much fruit. After all, an executive order from the US president isn’t easy to fight.

Interestingly, US-based companies came out in support of HUAWEI while simultaneously cutting commercial ties. Even Google declared that — if given the opportunity — it would want to continue working with HUAWEI. HUAWEI’s biggest telecom rival, Ericsson, also criticized the ban. In addition, tech industry analysts noted that the HUAWEI ban hurts US-based companies, too, because HUAWEI is such a massive business.

HUAWEI found out very quickly that it is not easy to overturn an executive order from the US president.

Eventually, China tried to turn the tables by threatening to create its own Entity List. HUAWEI then upped the ante by accusing the US of cyberattacks and employee harassment. However, the company supplied no evidence to support these accusations, and they led nowhere.

By mid-2020, HUAWEI had apparently accepted its fate. It stopped filing new lawsuits and stopped making any public declarations that it’s still trying to overturn the HUAWEI ban.

In 2021, though, with Trump’s exit from the White House, HUAWEI started making new attempts. HUAWEI founder Ren Zhengfei stated that he would welcome a chat with President Biden. Elsewhere, the company filed a new lawsuit against the FCC related to the HUAWEI ban. However, so far, these efforts have proved fruitless.

Full HUAWEI ban gets delays, license system established

Not even a week after Trump issued the executive order that kickstarted the HUAWEI ban, the US issued a 90-day reprieve of the ban’s full effects. This gave HUAWEI and its clients until August 19, 2019, to make arrangements for the weight of the ban.

As luck would have it, this 90-day reprieve would be extended three consecutive times. By February 2020, HUAWEI had had nearly a year of living without the full ramifications of the ban. That same month, the US government issued a final 45-day reprieve, allowing the HUAWEI ban to take full and permanent effect by April 1, 2020. Before that date arrived, Donald Trump signed a law banning rural US carriers from using HUAWEI equipment.

The US government gave HUAWEI nearly a year before the ban took full effect. Now, though, all bets are off.

While that was all happening, the US government rolled out a licensing system for US firms that wished to work with HUAWEI. The government allegedly received 130 applications for licenses but granted none of them. The government stated that licenses would go to companies whose work with HUAWEI would not pose a security threat. Google — which applied for one of these licenses — apparently didn’t fall into this category.

Towards the end of 2020, companies started to receive approval for partial deals with HUAWEI. Qualcomm, Sony, and Samsung can sell particular pieces of smartphone manufacturing parts to HUAWEI. However, these small wins won’t help the company return to business as usual.

Harmony OS: The alternative to Android

While HUAWEI cannot use Google-owned services and products in its phones, that doesn’t mean it can’t use Android itself. Android is an open-source operating system, which means that any person or company can use it for whatever they like without cost. However, many of the integral features of Android that users rely on aren’t included with “pure” Android and are actually owned by Google.

Theoretically, HUAWEI could indefinitely use Google-less Android to power its smartphones and tablets. In the background, though, HUAWEI claimed to have been working on a so-called “Plan B” operating system that would act as a fallback should a situation such as this HUAWEI ban ever come to pass. On August 9, 2019, the company launched “Plan B” as Harmony OS.

According to HUAWEI, Harmony OS is based on Linux, which is the same open-source platform on which Android is based. This means that Harmony and Android can share compatibilities. Theoretically, if a developer wished to do the work to make it compatible, any Android app can work within Harmony OS.

Initially, HUAWEI declared it would only use Harmony OS on Internet of Things (IoT) products. This means it would stick with Android for smartphones. However, the company later asserted that Harmony OS will become akin to a “HUAWEI OS” that will power pretty much everything it makes. This would free it from ever needing to be concerned about a HUAWEI-US ban again.

If any company can create a true rival to Android and iOS, it's HUAWEI.

Most would think that a new OS going up against Android and iOS is a fool’s errand. However, HUAWEI is so huge and has so much influence in China that it’s actually totally capable of pulling that off. Remember that, since Harmony OS is based on Linux, it would also be an open-source operating system. This means other companies could use Harmony OS instead of Android. It’s not at all out of the realm of possibility that other Chinese smartphone companies would adopt Harmony OS on at least some of their devices.

In early 2021, though, Ron Amadeo at Ars Technica gained beta access to an early version of Harmony OS. He discovered that, up until that point, Harmony OS was pretty much just Android 10 with a few cosmetic alterations. Eventually, HUAWEI launched some tablets with Harmony OS as its platform, and it will eventually launch new Harmony OS smartphones. It also will push Harmony OS to older products in its roster, effectively removing Google-powered Android from its entire portfolio.

HUAWEI Mate 30 series launches, first flagships without Google

If you’ll remember, the HUAWEI ban only affects products released after May 15, 2019. That means HUAWEI’s most recent flagship launch before that date — the HUAWEI P30 and P30 Pro, which launched on March 26, 2019 — continued to run the full suite of Google apps.

However, HUAWEI traditionally releases its Mate series — its other family of flagship phones — in the last half of the year. At first, rumors swirled that HUAWEI simply would skip the HUAWEI Mate 30 Pro launch. Ultimately, though, it went forward with the launch of a flagship phone without any Google apps whatsoever.

The HUAWEI Mate 30 Pro was the first bonafide flagship from the company to launch without any Google apps.

For the first few months, the phone was only available in China and several other smaller countries. Eventually, it made its way to the West (although not the US). The phones received stellar reviews, but few publications would recommend consumers buy the device due to its software shortcomings.

Unbelievably, the Mate 30 series still sold exceptionally well. Never underestimate the enormous population of China supporting one of their own. However, outside of China, the phone only made it into the hands of die-hard HUAWEI followers.

A workaround: HUAWEI repackages older devices

HUAWEI quickly found a loophole related to the HUAWEI ban and Google’s adherence to Trump’s executive order. The company realized that Google approves Android phones not based on their name or design but only on a few core components — most specifically, the processor. This means that HUAWEI could rebrand and repackage a phone that Google approved prior to the ban and resell it without violating the order.

Obviously, this wasn’t a long-term solution to the company’s woes. HUAWEI couldn’t perpetually re-release the P30 Pro over and over again, for example. However, that didn’t stop it from doing just that — twice. First, it issued two new colorways for the P30 Pro series, which it announced in September 2019. Then in early May 2020, it announced its intention to launch what it called the HUAWEI P30 Pro New Edition, which added yet another new colorway and lowered the price.

HUAWEI’s then-subsidiary HONOR also got into the re-release game by rebranding a few of its phones. Ultimately, this was a last-ditch effort to milk every dollar out of the most recently approved phones. Google and the US government made no publicized efforts to stop HUAWEI from doing this.

HUAWEI in 2020: A very different environment

Throughout 2019, HUAWEI probably hoped the US government would either weaken or remove the ban entirely. However, by the time 2020 came around, there were no indications that the HUAWEI ban was going to let up any time soon.

This put the company’s standing in the smartphone market in serious doubt. If you’ll remember, HUAWEI originally boasted in 2016 that it would be the world’s number-one smartphone manufacturer by the end of 2020. In early 2019, it was nearly a certainty that it would achieve that goal a full year ahead of schedule. Now, with the HUAWEI ban, the company’s long-running string of success was poised to come to a screeching halt.

Without Google apps on its phones, HUAWEI can't compete outside of China. In 2020, the company needed to start developing a way to fix that problem.

Although the Mate 30 series had sold well in HUAWEI’s native China and made comfortable sales throughout the rest of the world, it was no runaway success. Consumers outside of China simply aren’t ready for a premium smartphone that can’t access the Google Play Store or even popular third-party apps such as Uber.

HUAWEI’s answer to this was App Gallery — its proprietary Android apps store. Like the Play Store or Samsung’s Galaxy Store, App Gallery hosts a bunch of Android apps you can install on your phone. HUAWEI is spending millions on enticing developers to port their apps to App Gallery with varying degrees of success. While App Gallery has certainly come a long way in a short period of time, it’s by no means at all a solid replacement for the Play Store.

These efforts, though, paved the way for HUAWEI’s next flagship phones.

HUAWEI P40 and Mate 40 series: Still no Google

On March 26, 2020, HUAWEI unveiled the HUAWEI P40, P40 Pro, and P40 Pro Plus. The three phones feature all the flagship hardware one would expect from a P series device, including an absolutely incredible rear camera system.

On October 22, 2020, HUAWEI unveiled the Mate 40, Mate 40 Pro, and Mate 40 Pro Plus. These phones also were marvels when it comes to hardware and design.

Of course, none of the phones had Google apps. All the hardware in the world can’t make up for that.

As with the Mate 30 series, the P40 and Mate 40 series received great reviews. Once again, though, most publications — including Android Authority — advised against buying the phones due to the lack of Google services.

HUAWEI’s sales peak and then slide

You might think that throughout 2020, HUAWEI would have been struggling to stay afloat. However, HUAWEI actually made good on its promise and passed Samsung as the number one smartphone manufacturer as assessed by units shipped.

How is this possible? As mentioned before, you should never underestimate the power of 1.4 billion Chinese citizens all backing up their beloved homegrown brand. Also, don’t forget that HUAWEI doesn’t just make smartphones. It also still supplies networking systems to multiple countries all around the world.

However, HUAWEI couldn’t sustain that momentum forever. By the end of 2020, the company saw its market share dwindle. Samsung once again became the world’s largest smartphone manufacturer. Meanwhile, 2021 proved to be a dismal year for HUAWEI’s smartphone division. HUAWEI dropped out of the top-five smartphone OEMs by the end of Q1 2021 and limited the HUAWEI P50 series to China only. Now, in 2023, HUAWEI is not even among the top ten global smartphone manufacturers.

HUAWEI ban brings the end of Kirin chipsets

Unlike many smartphone manufacturers, HUAWEI almost exclusively uses its own chipsets in its smartphones and tablets. Its Kirin processors are designed by HUAWEI and then produced by a company called TSMC.

At first, TSMC assured HUAWEI — and the tech industry in general — that it would continue to produce HUAWEI’s Kirin chipsets. However, it rolled back on that declaration, likely because the HUAWEI ban was now in full effect (i.e., all the extensions are over).

Without TSMC, HUAWEI is essentially unable to create Kirin chipsets. At first, we assumed the Mate 40 would be the final phone launched with a Kirin chipset. However, rumors abounded that the 2021 HUAWEI P50 could have the same Kirin processor as the Mate 40. It turns out that HUAWEI went half-and-half, with some P50 models having leftover Kirin chips while others have Qualcomm chips.

There aren’t many other companies out there that could create processors for HUAWEI that don’t involve US-based companies or equipment. The only real option is MediaTek, a Taiwanese firm. As such, it’s very likely we’ll see HUAWEI flagships with MediaTek chips in the future.

HUAWEI sells off HONOR sub-brand

Although HUAWEI’s sub-brand HONOR operated semi-independently, it was still officially part of the HUAWEI family. This meant that the effects of the HUAWEI ban carried over to it. In November 2020, HUAWEI sold off HONOR to a Chinese company called Shenzhen Zhixin New Information Technology Co.

In an official statement on the matter, HUAWEI attributed the quick sale to the “tremendous pressure” it’s under from the US government.

With the completion of this sale, HONOR will have no direct connection to HUAWEI. This will free it up to act as its own brand without any of the limitations related to the US sanctions.

In late January 2021, HONOR launched its first phone since leaving HUAWEI: the HONOR V40. However, it and a few other phones it launched since are China-exclusive. HONOR said the HONOR Magic 3 series would have Google apps onboard and land in Western countries. That never happened, however. It said the same thing in 2022 for the Magic 4 series but actually followed through this time. HONOR’s most recent phone is the Magic 5 series, launched in early 2023. The series comes with Google apps.

2021 and beyond: Can HUAWEI survive?

HUAWEI has had a rocky time since May 15, 2019, to put it mildly. So far, it’s weathered the storm pretty well. However, how long can it keep the ship afloat with so much stacked against it?

HUAWEI knows that no matter what, the HUAWEI-US ban can’t touch its Chinese business. The company is so beloved in China that it could become a China-only brand and survive handily for decades. HUAWEI isn’t the kind of company that would roll over that easily, though.

As far as we can tell, HUAWEI plans to move forward with its usual plans of releasing at least one major flagship phone each year and other smaller launches whenever it’s appropriate. It can’t use Google apps, but it can still use Android. The Play Store is off-limits, but App Gallery is getting stronger. It can’t make its own processors, but there are other companies from which it can buy chips.

The question then becomes how long the company can keep this up before the smartphone division loses more money than it makes. But don’t write HUAWEI off — it’s already proven it can survive things that many other companies couldn’t.

Do you currently own a HUAWEI phone?

If you currently own a HUAWEI or HONOR phone, you might have some questions about how the HUAWEI ban affects you. Below are some frequently asked questions.

HUAWEI is almost certainly tracking how you use your device — but every smartphone company does this. Smartphone OEMs want to know how often you unlock your phone, charge it, open certain apps, etc., so they can use that info to make better products. However, do not be scared that HUAWEI is actively monitoring you specifically for nefarious purposes. There has never been any evidence to support this claim.

It’s not illegal to own a HUAWEI device anywhere in the world. The HUAWEI ban prevents HUAWEI from working with US-based companies in the creation of its products. It doesn’t apply to consumers who currently own a HUAWEI product and doesn’t prevent them from buying new ones, either.

As long as there are no laws in your location preventing it, you’re free to sell your HUAWEI device. Trump’s executive order says nothing about reselling used HUAWEI products.

You don’t need to worry about this. Although your phone obviously won’t last forever, HUAWEI will not “brick” your device. You can continue using it for as long as it’s physically capable.

This is a tricky question. If you own a Google-less HUAWEI device launched after June 2019, you’ll continue to see Android upgrades and security patches on the schedule to which HUAWEI commits for that particular device. However, if you own a HUAWEI phone with Google services onboard launched before May 2019, the HUAWEI ban prevents the company from issuing Google-sanctioned updates going forward. HUAWEI has iterated its commitment to delivering patches and upgrades moving forward in spite of this, but there are no long-term guarantees.

Yes. Many companies offer apps and services that do this for you, including Samsung and OnePlus, for example. Keep in mind that some forms of data and some apps won’t be available across different devices, but almost all of your data will transfer successfully.

Please recycle your smartphone using the proper methods. This is a great resource for ethically disposing of your used electronics.

Should you avoid buying HUAWEI phones or other products?

HUAWEI has already released multiple high-profile smartphones since the HUAWEI-US ban took effect. We fully expect there to be more phones on the way, too. As such, you might want to buy a HUAWEI phone even though the ban would prevent it from being a “normal” experience.

Here are the answers to some questions you might have about buying a new HUAWEI device.

Yes, it is perfectly legal to buy new HUAWEI products of all kinds. The HUAWEI ban only prevents HUAWEI from working with US-based companies. This might affect the hows and wheres of buying a HUAWEI phone, but it has no effect on your purchase or ownership of the device.

Yes, you can do all those things and more. The only difference will be the apps you use to perform those functions will probably be different than the ones you currently use. For example, Google Chrome will not be available on new HUAWEI phones, so you’ll need to use a different app for browsing the web. HUAWEI’s app store (called App Gallery) will have many of the apps you need.

You can sideload Android apps onto HUAWEI phones, and a lot of them will work correctly. However, many prominent apps use something called Google Play Services to function. This Google product won’t be on new HUAWEI phones. There are several methods that have been used to sideload Google Play Services on HUAWEI phones successfully, but these are extremely unofficial, could potentially damage your phone, have no guarantee of working long-term, and potentially leave your device open to security risks. We do not recommend using this as a viable solution.

HUAWEI is spending millions of dollars on convincing app developers to port their products to App Gallery. As such, there are a lot of Android apps already available through App Gallery. HUAWEI adds more all the time. You can install App Gallery on your current Android phone and search for the apps you depend on the most, which should help you decide if it can fully replace the Play Store.

Yes, in almost all cases. HUAWEI devices still run on Android, and Bluetooth is a cross-platform service, so everything should function as you would expect. Obviously, there’s no way to say every single device will work perfectly, but most everything should work.

Huawei's use of Android restricted by Google

Google has barred the world's second biggest smartphone maker, Huawei, from some updates to the Android operating system, dealing a blow to the Chinese company.

New designs of Huawei smartphones are set to lose access to some Google apps.

The move comes after the Trump administration added Huawei to a list of companies that American firms cannot trade with unless they have a licence.

Google said it was "complying with the order and reviewing the implications".

Huawei said it would continue to provide security updates and after-sales services to all existing Huawei and Honor smartphone and tablet products, covering those that have been sold or are still in stock globally.

"We will continue to build a safe and sustainable software ecosystem, in order to provide the best experience for all users globally," it added.

In a press briefing, China said it "supports the relevant company [Huawei] to defend its legitimate rights according to law".

Existing Huawei smartphone users will be able to update apps and push through security fixes, as well as update Google Play services.

But when Google launches the next version of Android later this year, it may not be available on Huawei devices.

Future Huawei devices may no longer have apps such as YouTube and Maps.

Huawei can still use the version of the Android operating system available through an open source licence.

Ben Wood, from the CCS Insight consultancy, said the move by Google would have "big implications for Huawei's consumer business".

UK mobile trade body Mobile UK said it was "working closely with relevant authorities to understand the implications of the US Department of Commerce's placement of Huawei on its Entity List."

Last Wednesday, the Trump administration added Huawei to its "entity list", which bans the company from acquiring technology from US firms without government approval.

In his first comments since the firm was placed on the list, Huawei chief executive Ren Zhengfei told Japanese media on Saturday: "We have already been preparing for this."

He said the firm, which buys about $67bn (£52.6bn) worth of components each year according to the Nikkei business newspaper, would push ahead with developing its own parts.

Huawei faces a growing backlash from Western countries, led by the US, over possible risks posed by using its products in next-generation 5G mobile networks.

Several countries have raised concerns that Huawei equipment could be used by China for surveillance, allegations the company has vehemently denied.

Huawei has said its work does not pose any threats and that it is independent from the Chinese government.

However, some countries have blocked telecoms companies from using Huawei products in 5G mobile networks.

So far the UK has held back from any formal ban.

"Huawei has been working hard on developing its own App Gallery and other software assets in a similar manner to its work on chipset solutions. There is little doubt these efforts are part of its desire to control its own destiny," said Mr Wood.

US chipmakers including Intel, Qualcomm and Broadcom are reported to have told their workers they will stop supplying Huawei, according to Bloomberg.

Intel would not to comment to the BBC.

Rosenblatt Securities analyst Ryan Koontz said Huawei would be "seriously crippled" if it did not have these "key US components", although the Chinese firm is believed to have stockpiles in place.

California-based Xilinx said it was aware of the order by the Trump administration and was "co-operating" but had nothing to add.

Outside the US, Taiwan Semiconductor Manufacturing Company (TSMC) is continuing to deliver to Huawei.

The Nikkei reported that TSMC had said it owned a "complicated and sophisticated export control compliance system" and "based on the data in the system we are not changing our shipping practice for the time being".

By Leo Kelion, BBC Technology desk editor

In the short term, this could be very damaging for Huawei in the West.

Smartphone shoppers would not want an Android phone that lacked access to Google's Play Store, its virtual assistant or security updates, assuming these are among the services that would be pulled.

In the longer term, though, this might give smartphone vendors in general a reason to seriously consider the need for a viable alternative to Google's operating system, particularly at a time that the search giant is trying to push its own Pixel brand at their expense.

As far as Huawei is concerned, it appears to have prepared for the eventuality of being cut off from American know-how.

Its smartphones are already powered by its own proprietary processors, and earlier this year its consumer devices chief told German newspaper Die Welt that "we have prepared our own operating systems - that's our plan B".

Even so, this move could knock its ambition to overtake Samsung and become the bestselling smartphone brand in 2020 seriously off course.

The latest move against Huawei marks an escalation in tensions between the firm and the US.

The company is facing almost two dozen criminal charges filed by US authorities. Washington is also seeking the extradition of Huawei executive Meng Wangzou from Canada, where she was arrested in December at the behest of American officials.

It comes as trade tensions between the US and China also appear to be rising.

The world's two largest economies have been locked in a bruising trade battle for the past year that has seen tariffs imposed on billions of dollars worth of one another's goods.

Earlier this month, Washington more than doubled tariffs on $200bn of Chinese goods, prompting Beijing to retaliate with its own tariff hikes on US products.

The move surprised some - and rattled global markets - as the situation had seemed to be nearing a conclusion.

The US-China trade war has weighed on the global economy over the past year and created uncertainty for businesses and consumers.
