Trump prepares to slap tariffs on semiconductors and pharma
The topsy-turvy-tariff tale continued to swing this week, as the Trump administration advanced a plan on Monday that could result in new levies on semiconductors and pharmaceuticals. The news came days after US President Donald Trump announced that smartphones would be exempt from the 145% duty that he had slapped on China.
Officially, the plan involves a first step of investigating the national security implications of importing pharma and semiconductors. The next step would be to invoke Section 232 of the 1962 Trade Expansion Act, which allows a president to impose tariffs in the interests of protecting national security. As such, the means for this latest slate of levies would be different from the widescale duties announced on “liberation day.”
Countries affected. The United States relies heavily on Taiwan in particular for semiconductors — one plant there crafts 92% of the world’s advanced chips. As for pharmaceuticals, the US imports many from China, Ireland, and India.
All that and a bag of CHIPS. Former President Joe Biden tried to spark the US’s own semiconductor industry with the 2022 CHIPS and Science Act, which allocated $53 billion for domestic semiconductor manufacturing. Trump said last month he wanted to “get rid of” the CHIPS Act, yet his more recent actions suggest he’s interested in leveraging the law to further his plan to reduce US reliance on foreign chips.The flag of China is displayed on a smartphone with a NVIDIA chip in the background in this photo illustration.
Nvidia delays could slow down China at a crucial time
Chinese tech giants like Tencent, Alibaba, and ByteDance are buying chips as they race to build AI systems that can compete with American companies like OpenAI and Google. The shortage means these companies might face serious delays in launching their own AI projects, some of which are based on the promising Chinese AI startup DeepSeek’s open-source models.
It also comes at a critical time when China is pouring resources into developing its own AI industry despite having limited access to the most advanced computing technology due to US trade restrictions. New shipments are expected by mid-April, though it could mean months of waiting for Chinese firms to go through the proper channels.
Did Biden’s chip rules go too far?
The “AI Diffusion Rule,” which was announced on Jan. 13 by the last administration, divides countries into three tiers with varying restrictions on American AI chip imports. While close allies like Canada and the UK face few limits, many partners, including India, Switzerland, and Israel, fall into the second tier with significant restrictions on how many chips they can order. A third tier of rivals like China and Russia are completely cut off.
Microsoft’s critique
Microsoft Vice Chair and President Brad Smith didn’t mince words. The rule “undermines” US AI leadership and will ultimately give “China a strategic advantage,” he wrote in a blog post. Smith argued that the rule’s restrictions on allies would backfire, forcing countries to look elsewhere for AI infrastructure — likely to China. While Microsoft waited until now, Nvidia criticized the rule immediately after it was announced, saying that it “threatens to derail innovation and economic growth worldwide.”
The goal of Biden’s export controls has been clear: prevent China from accessing cutting-edge AI infrastructure needed to train and deploy top models while maintaining sales to friendly markets. While Biden’s chip controls began in 2022, the AI Diffusion Rule represents the broadest attempt to prevent advanced computing power from reaching China.
What the Diffusion rule accomplishes
Xiaomeng Lu, director of geo-technology at Eurasia Group, sees the rule as “a move to alienate US allies and partners.” While the Trump administration might tighten rules for China, it could potentially relax them for other countries, she says.
Jeremy Mark, a nonresident senior fellow at the Atlantic Council's GeoEconomics Center, said the implementation seemed rushed. ”As with any wide-reaching policy that is put together in a rush, there will be unintended consequences.”
Jacob Feldgoise, a data research analyst at Georgetown University’s Center for Security and Emerging Technology, questions the primary assumptions of all of Biden’s export controls on chips. “They assume that compute scaling will continue and that algorithmic improvements can’t substitute for compute,” he said. “If those assumptions break down, the controls will further struggle to control the spread of AI capabilities.”
The loopholes in the plan
The Biden export controls haven’t worked as expected. The Chinese company DeepSeek has claimed that it has trained an industry-standard model with much fewer chips than top US labs, though the US is currently investigating whether it had access to restricted chips.
Meanwhile, Chinese buyers have been circumventing the export rules anyway. On Sunday, the Wall Street Journal published an investigation that found Chinese firms ordering Nvidia’s Blackwell AI chips through third parties in neighboring countries. And underground markets across China have long sold Nvidia chips sourced from unknown places.
What Trump could do
Mark said thatTrump could “tighten restrictions on technology sales to China even more than Biden” but said it’s impossible to tell what will come through as policy and what is posturing for future negotiations.
Feldgoise believes further tightening on China is likely, but notes that softening the policy on other countries could undermine that effort. “The challenge with loosening controls on other countries is that doing so would likely undermine the administration's objective of cracking down on chip smuggling to China.”
Domestic chip production and cutting off China will likely remain priorities under Trump, continuing two rare areas of bipartisan agreement. Silicon Valley has been ingratiating itself with the Trump administration in recent months and, on this front, hopes that deregulation in key areas could clear the way for better sales around the world.In this photo illustration, Intel logo is displayed on a smartphone with stock market percentages on the background.
Intel’s suitors are swarming
Intel has publicly struggled to innovate in recent years, missing out on a windfall from artificial intelligence enjoyed by rivals.
While many semiconductor companies either design chips or manufacture them, Intel is an integrated device manufacturer — meaning, it does both. That said, it lost ground to chip-designing rivals like Nvidia and AMD and fabrication competitors like Taiwan Semiconductor Manufacturing Company and GlobalFoundries during the AI boom. As such, Intel’s stock has fallen 47% in the past year and 63% in the past five years.
Now, the vultures are circling. Broadcom is reportedly eyeing Intel’s chip design and marketing business while TSMC is considering bidding for some or all of Intel’s chip plants.
The proposed deals are still preliminary, but they come amid continuous struggles for Intel, which culminated in the resignation of its CEO Pat Gelsinger in early December. Even before that, in September, Qualcomm also inquired about a potential sale.
Any deal for Intel would be highly scrutinized by the US Department of Justice and the Federal Trade Commission, America’s two antitrust authorities, but also potentially considered for any national security ramifications, considering chip independence is a strategic priority for the US.
For now, Intel is still standing, but it very may be carved up in the months and years to come.
Is DeepSeek the next US national security threat?
Before DeepSeek released its R1 model last month, America’s long-term AI dominance felt like a sure thing.
DeepSeek is a Chinese startup, born from a hedge fund, that claims to have used a fraction of the computing power of US competitors while making an artificial intelligence model that rivals the best that Northern California’s labs have to offer. Critics have alleged that the company has been dishonest about claims it only spent $6 million training the model. But for anyone taking DeepSeek at face value, it has been a revelation that sent shockwaves not only through Silicon Valley but also through Wall Street and Washington.
The Biden administration spent the past few years clamping down on powerful US-made chips flowing into China, but evidently, DeepSeek figured out how to build a great model with a dearth of high-tech resources.
“It shines a spotlight on the limits of the US export control system,” said Xiaomeng Lu, geo-technology director of Eurasia Group. “Technology has evolved in a way that regulators failed to anticipate.”
“Necessity is the mother of invention” – that’s how Jack Corrigan of Georgetown’s Center for Security and Emerging Technology put it. “US efforts to hobble China’s AI sector created a need for Chinese developers to innovate a more efficient approach to AI.”
But DeepSeek’s impact goes beyond its own efficiency. It’s an open-source model, meaning its code is available for anyone to use and modify. “Due to the open-source nature of their model, it will be much harder to restrict access to it entirely,” said Valerie Wirtschafter, a fellow at the Brookings Institution. “The other more pragmatic question is whether Congress has the appetite for more whack-a-mole-style tech regulations, given the chaos that has unfolded since the passage of the TikTok ban.”
US government agencies such as NASA and the Navy have banned DeepSeek models on their devices, as did Congress, but there’s been no US effort to try and ban it more widely among the public, as Italy did on Thursday, citing unresolved data privacy concerns. And America’s top cloud providers, including Microsoft Azure and Amazon Web Services, have already added access to R1.
Justin Sherman, founder of Global Cyber Strategies, says that the Trump administration has a toolbox to “screen, restrict, and even expel non-US tech from the US tech supply chain on national security grounds,” particularly through the Commerce Department’s Information and Communications Technology and Services. Still, he cautions against letting “stock market temperaments, reductive China panic in Washington, and media overinflation of industry AI claims” steer nuanced policy decisions.
DeepSeek’s true threat is likely strategic rather than technical. “DeepSeek’s latest model raises the question of what happens if China becomes the leader in providing publicly available, freely downloadable AI models,” said Sam Winter-Levy, a fellow at the Carnegie Endowment for International Peace. “While the US is obsessed with the race to see who can build the single biggest and most powerful model, perhaps even artificial general intelligence, the Chinese might win the race to see who can build really useful and cost-effective models that will be used by people and companies around the world.” At a minimum, China’s overnight success has quickly leveled the playing field for US-China competition over technology.
Perhaps then the answer to DeepSeek requires a rethinking of what American dominance in AI really means. Banning any specific app or model would just be a Band-Aid on a bullet wound.

What DeepSeek means for the US-China AI war
A Chinese startup might have achieved what many thought was impossible: matching America’s best artificial intelligence systems at a fraction of the cost.
DeepSeek's latest AI model, DeepSeek-R1, was released earlier this month. The open-source model performs as well as top models from OpenAI and Google while using just a fraction of the computing power and cost to develop; it’s also a fraction of the cost to use.
DeepSeek claims that it only needed $6 million in computing power to develop the model, which the New York Times notes is 10 times less than what Meta spent on its model. The R1 model received the fourth-highest score on Chatbot Arena, which crowd-sources evaluations to rank large language models by capability, only behind two of Google’s Gemini models and ChatGPT-4o and ahead of Anthropic’s Claude 3.5 Sonnet.
If you take DeepSeek at its word, then China has managed to put a major player in AI on the map without access to top chips from US companies like Nvidia and AMD — at least those released in the past two years. Joe Biden’s administration placed strict export controls on these chips, so if the company has had access it may not be forthright about that.
For now, the US markets are indeed taking DeepSeek at its word. Nvidia stock fell nearly 17% on Monday, erasing a record sum from its market capitalization — $589 billion in a single day. The Nasdaq stock exchange ended the day down 3%, as a result.
The revelation about DeepSeek has come as Donald Trump tries to spur AI infrastructure in the United States, heralding the $500 billion Stargate project. But China’s new open-source model might have just changed the landscape when many thought the United States was running away with the race.
In a speech Monday evening, Trump called news of the DeepSeek model a “positive” due to its cheap cost but said American industry needs to compete. “The release of DeepSeek, AI from a Chinese company should be a wakeup call for our industries that we need to be laser-focused on competing to win.”Biden has one week left. His chip war with China isn’t done yet.
On Monday, the US Commerce Department announced new export controls on advanced chips used to train and run artificial intelligence, the latest in a series of increasingly tough restrictions enacted by the Biden administration in the past few years. It’s primarily a mechanism for maintaining American dominance in artificial intelligence while also cutting off adversaries — first and foremost China — from access to the chips they need to level the playing field commercially and militarily.
Under the new export regime, the US will use a three-tier system: Companies from the US and 18 close allies, including the UK, Germany, and Japan, are fully free to buy these chips. Those from countries subject to US arms embargo, such as China and Russia, are completely cut off from acquiring high-powered chips. And countries from every other country will face a set cap restricting the number of AI processors they can buy each year without special permission. This latter group even includes strategic partners such as Mexico, Switzerland, and Israel.
“This policy will help build a trusted technology ecosystem around the world and allow us to protect against the national security risks associated with AI, while ensuring controls do not stifle innovation or US technological leadership,” US Secretary of Commerce Gina Raimondo said in a press release.
But the chip industry isn’t happy — particularly America’s most important chip designer, Nvidia, which said that the rules are “misguided.”
“While cloaked in the guise of an ‘anti-China’ measure, these rules would do nothing to enhance US security,” Ned Finkle, Nvidia’s vice president of government affairs, wrote in a statement. “Rather than mitigate any threat, the new Biden rules would only weaken America’s global competitiveness, undermining the innovation that has kept the US ahead.” The Semiconductor Industry Association criticized the timing — just days before the presidential transition.
Tinglong Dai, a professor at Johns Hopkins Carey Business School, said that US companies are increasingly aligned with national security concerns and “face ever greater challenges to making a profit or even operating in China.” In that way, he said he expects that short-term discomfort will give way to companies falling in line with national security priorities.
Xiaomeng Lu, director of geo-technology at Eurasia Group, expressed concern about implementation. “Under this regime, only a small number of trusted allies have unrestricted access to high-end semiconductors,” she said. “Data centers located in over 100 countries will have to apply for licenses through an onerous process, even if they are owned and operated by US cloud service providers.” She added that the rules could discourage many countries from buying US products.
“This rule is not just about China, but it may make China’s chip smuggling efforts more difficult,” said Jacob Feldgoise, a data research analyst at Georgetown’s Center for Security and Emerging Technology. “The regulation could hurt American businesses, including AI chip companies and cloud service providers, but perhaps more importantly, the rule may hurt the United States’ relationship with a set of allies to which the rule didn’t give preferential treatment.”
Jeremy Mark, a nonresident senior fellow at the Atlantic Council’s GeoEconomics Center, said that China is deeply embedded in the semiconductor supply chain, such as supplying important rare earth metals to chip makers. In this way, the US is risking a “serious trade conflict” in further cutting off China.
But there may be more to the story. “There has been clear, bipartisan support in Washington for export controls, and that has empowered several government agencies to act,” Mark said. “However, it’s not clear how much the latest initiatives have been driven by a White House decision to hand Trump a fait accompli.”
Trump won’t want to appear weak on China, but he also doesn’t want to alienate important industry players. Dai said he expects Trump to maintain a tough stance on China and to “tweak the current export rules — because he’s Trump after all.” The rule doesn’t go into effect for companies until May 15, Feldgoise noted, giving Trump time to revise the rules if needed.
As for China, the country is forging ahead even without access to the top chips. Recently, the Chinese startup DeepSeek released an open-source large language model that has impressed outsiders. This development proves it’s “possible to build a quality model with less advanced chips,” Lu said. Meanwhile, the new Commerce Department restrictions will “undermine US companies’ competitiveness in the face of robust competition from China,” she adds.The NVIDIA logo seen at the American GPU manufacturer NVIDIA Taipei office.
Nvidia forges deals in American Southwest and Southeastern Asia
The California-based chip giant is negotiating with Taiwan Semiconductor Manufacturing Company, or TSMC, the world’s top contract chipmaker, to manufacture its top-of-the-line Blackwell AI processors at TSMC’s Arizona facility. TSMC has invested billions to bring its high-tech manufacturing to the Southwest US, thanks in part to a $6.6 billion cash infusion from the Biden administration as part of the CHIPS and Science Act. Apple and AMD have reportedly already signed on to get their chips made in the Arizona plant when it starts production in the first half of 2025. That said, the chips won’t be entirely made in America: Final packaging is done back in Taiwan, which complicates and prolongs an already lengthy manufacturing process.
Halfway around the world, Nvidia CEO Jensen Huang met with the Thai and Vietnamese prime ministers last week as the company makes inroads in Southeast Asia. Nvidia also announced plans to establish Nvidia’s first research and development center in Vietnam, along with the acquisition of Vietnamese healthcare startup VinBrain for an undisclosed sum. In Thailand, the company signed a cloud deal with a company called SIAM.AI Cloud. Huang also emphasized the importance of “sovereign AI,” meaning that every country should have its own AI infrastructure and models.
In China, however, Nvidia is facing new scrutiny: The State Administration of Market Regulation is reportedly investigating whether the chipmaker violated antitrust laws when it acquired the Israeli-American company Mellanox in 2020. China previously gave conditional approval of the nearly $7 billion deal, but more than four years later, with the US restricting Nvidia from selling its most powerful chips to Chinese companies, the country is seeking new ways to gain leverage. A Nvidia spokesperson said the company is “happy to answer any questions regulators may have about our business.”
