The administration of US President Joe Biden plans to tighten export controls announced in October last year to restrict sales of some artificial intelligence (AI) chips to China, amid growing concerns about selling the technology to a key strategic competitor, people familiar with the matter said.
Under the US Department of Commerce proposal, expected next month, Washington would revise export controls to make it harder to sell some chips to China without a license.
The move is aimed in part at Nvidia Corp’s A800 chip, which the US-based company designed after the earlier controls were announced.
The product’s configuration comes just within those limits.
Nvidia chief financial officer Colette Kress on Wednesday said that the company is aware of the reports on tighter restrictions.
Strong overall demand for its products means that there would be no material impact on the company’s earnings if such rules are introduced, Kress said at an online investor event.
China represents about 20 to 25 percent of Nvidia’s data center revenue, and — in the long term — any ban on exports to that country would represent a loss of opportunity, she said.
Plans for tighter controls were reported earlier by the Wall Street Journal.
In a briefing on Wednesday, Chinese embassy spokesman Liu Pengyu (劉鵬宇) cited the Biden administration’s moves in the semiconductor industry as an example of a lack of respect that has prevented Washington and Beijing from discussing other issues.
“Communication first requires mutual respect and communication must deliver results,” Liu said. “We know that there are disputes in the semiconductor industry, but we haven’t seen any positive initiatives from the US side to say: ‘OK, how about we have communication on this issue?’”
After sliding early in the session, Nvidia shares recouped much of their losses on Wednesday.
The stock was down about 1.8 percent at the close in New York.
It was not clear whether the announcement would include an extension of general licenses given to Taiwanese and South Korean companies.
Taiwan Semiconductor Manufacturing Co (台積電), Samsung Electronics Co and SK Hynix Inc in October last year won a one-year reprieve from the restrictions and have asked the White House to extend them by at least another year.
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday obtained the government’s approval to inject an additional US$7.5 billion into its US subsidiary, the Department of Investment Review said in a statement. The department approved TSMC’s application of investing in TSMC Arizona Corp, which is engaged in the manufacturing, sales, testing and design of IC and other semiconductor devices, it said. The latest capital injection follows a US$5 billion investment for TSMC Arizona approved in June. The chipmaker has broken ground on two advanced fabs in Arizona with aggregated investments approved by the department totaling US$24 billion thus far. According to TSMC, the first Arizona
The lethal hack of Hezbollah’s Asian-branded pagers and walkie-talkies has sparked an intense search for the devices’ path, revealing a murky market for older technologies where buyers might have few assurances about what they are getting. While supply chains and distribution channels for higher-margin and newer products are tightly managed, that is not the case for older electronics from Asia where counterfeiting, surplus inventories and complex contract manufacturing deals can sometimes make it impossible to identify the source of a product, analysts and consultants say. The response from the companies at the center of the booby-trapped gadgets that killed 37
FRIENDLY TAKEOVER: While Qualcomm Inc’s proposal to buy some or all of Intel raises the prospect of other competitors, Broadcom Inc is staying on the sidelines Qualcomm Inc has approached Intel Corp to discuss a potential acquisition of the struggling chipmaker, people with knowledge of the matter said, raising the prospect of one of the biggest-ever merger and acquisition deals. California-based Qualcomm proposed a friendly takeover for Intel in recent days, said the sources, who asked not to be identified discussing confidential information. The proposal is for all of the chipmaker, although Qualcomm has not ruled out buying some parts of Intel and selling off others. It is uncertain whether the initial approach would lead to an agreement and any deal is likely to come under close antitrust scrutiny
SECURITY CONCERNS: The proposed ban on Chinese autonomous vehicle software and hardware would go into effect with the 2027 and 2030 model years respectively The US Department of Commerce today is expected to propose prohibiting Chinese software and hardware in connected and autonomous vehicles on US roads due to national security concerns, two sources said. US President Joe Biden’s administration has raised concerns about the collection of data by Chinese companies on US drivers and infrastructure as well as the potential foreign manipulation of vehicles connected to the Internet and navigation systems. The proposed regulation would ban the import and sale of vehicles from China with key communications or automated driving system software or hardware, said the two sources, who declined to be identified because the
