According to the [1]Wall Street Journal , the state-backed China's Academy of Engineering Physics CAEP) has likely used back channels and shell companies to obtain US chips for use in nuclear weapons simulations and other applications.
The CAEP shares much in common with the US Department of Energy. Both agencies are tasked with the development and maintenance of the nation's strategic weapons stockpile. Since underground nuclear weapons tests were banned in 1996, such work has often been done with supercomputers designed to simulate various aspects of nuclear weapons' testing.
[2]
In an effort to prevent the use of US chips for military applications in 1997 the US added the CAEP to the Commerce Department's [3]Entity List of organizations that aren't allowed to import certain technologies. However, as the WSJ investigation found, these efforts appear to have done little to stop Chinese agencies with ties to the military obtaining US-made chips.

[5]
The Journal uncovered more than 30 papers published by CAEP researchers that made use of American semiconductors, including several with direct military applications.
The findings underscore just how ineffective the US Commerce Department's measures have been and builds on a WSJ [6]investigation from last year that found that the US approved 94 percent of licenses required to export restricted goods to China.

Part of the problem is the US export bans only restrict the sale of goods to specific entities — usually those with ties to foreign militaries. As highlighted in the WSJ report, many of these goods are widely available in servers and PCs sold in the Chinese market.
This creates an opportunity for shell companies owned by the Chinese government to subvert US export bans. And while the US Commerce Department has worked to shutout shell companies as soon as it finds them, we imagine it's a bit like Whac-A-Mole, but with mushroom-cloud consequences.
[11]
Making matters more complicated, many gaming-focusing graphics cards share the GPU die used in chipmaker's datacenter products. For example, the GTX 1080 TI, one of the GPUs used for CAEP research, shares the same die as Nvidia's datacenter focused Tesla P40, albeit with minor differences like memory, clocks and shader counts.
The same is true today, with Nvidia's RTX 4090 sharing the same GPU die — the AD102 — as its L40 accelerator. And while the WSJ didn't find any evidence to suggest the Chinese had acquired current-generation chips in the past two years, there's no reason to think they won't.
In fact, recent [12]changes by the US Commerce Department could incentivize agencies like CAEP to do just that. Over the past two years, the US has ramped up efforts to cripple China's domestic semiconductor industry, while leaning on US-held patents and licenses to prevent Chinese chipmakers from producing chips in Taiwanese and Korean fabs.
[13]
In October, the Department revised its entity list, adding more than two dozen Chinese firms and imposing more generalized restrictions of [14]AI chips and accelerators , including Nvidia's A100 and AMD's Instinct MI250, to China. The measures reportedly caused problems for Chinese GPU vendor Biren, which relies on TSMC for manufacturing.
The chip startup quickly [15]retooled its design, capping the chip's transfer rate to 576GBps, down from 640GBps to avoid scrutiny. Nvidia employed a similar strategy to get around US export bans, rereleasing its A100 as the A800 with a narrower memory bus.
It's also worth noting that while CAEP has long held a place on the US Entity List, the same hasn't been true of many Chinese supercomputing centers. The National Supercomputing Center in Guangzhou province, home to the number [16]10-ranked TianHe-2 supercomputer on the Top500 ranking, was only added to the Entities list in 2015. The decision came after the US became aware the Intel-based system has been used in " [17]nuclear activities ."
The US Commerce Department in 2021 added a slew of other Chinese supercomputing centers to the Entity List over suspicious the systems were being used by China's military actors to support [18]military modernization efforts and nuclear weapons programs. ®

Re: Seriously....
No, they're not. The People's Republic of China's most advanced chipmaker is SMIC, and while they recently appear to have developed a 7nm process, that process doesn't involve the use of Extreme Ultraviolet Lithography, EUV.
Advanced western chips from Intel are made in the United States, Israel - and some of them are made for it by TSMC now.
Some Nvidia chips are made for it by Samsung, and the rest are made by TSMC.
TSMC is not in the People's Republic of China, and the U.S. can indeed request that the government of the sovereign state in which it is located not allow exports of chips made with their advanced technology to the People's Republic of China. They have made such a request, and that country's government has acceded to that request.
Of course, there is an understandable possible source of your confusion. TSMC stands for Taiwan Semiconductor. The official name of the country usually referred to as Taiwan is, of course, the Republic of China.
So in a way, you're correct. Chips made by TSMC are made in the historic nation of China. However, while both the People's Republic of China and the Republic of China are part of the historic nation of China, that doesn't mean that they are one country under one government. Even though the People's Republic of China does indeed make a territorial claim to Taiwan.
The two countries issue their own passports. The People's Republic of China harasses the Republic of China by intruding into its airspace and territorial waters with military airplanes and naval vessels. Xi Jinping is the leader of the People's Republic of China. Tsai Ing-Wen is the leader of the Republic of China.
China is a Big Country
As long as you can walk into a computer store and buy an Nvidia graphics card off the shelf, then obviously people acting on behalf of the Chinese military are going to be able to walk into a computer store and do just that, too. Of course, many of the sanctioned Western devices of interest are for use in servers rather than home computers, which is why shell companies are involved - but of course this sort of thing can be easily done since the government of the PRC obviously has no interest in enforcing U.S. sanctions against its own military.
Thus, the only real cure is to have a 100% ban on shipping advanced Western technology to anyone in the PRC. Our computers, our smartphones, our video cards, and so on... will just have to be assembled in Malaysia, Indonesia, or India instead of China.
Seriously....
The f*c*i*g chips are made in China. How the f**k does the US government expect to prevent Chinese use of any of these chips?
