China urges local firms not to use Nvidia's H20 chips, Bloomberg News reports
Authorities have sent notices to a range of firms discouraging use of the less-advanced semiconductors, with the guidance taking a particularly strong stance against the use of Nvidia's H20s for any government or national security-related work by state enterprises or private companies, the report said.
Reuters could not immediately confirm the report. Nvidia did not immediately respond to a request for comment outside regular business hours.
Nvidia said in July that its products have no "backdoors" that would allow remote access or control after China raised concerns over potential security risks in the chipmaker's H20 artificial intelligence chip.
US President Donald Trump suggested on Monday that he might allow Nvidia to sell a scaled-down version of its next-generation advanced GPU chip, Blackwell, in China, despite deep-seated fears in Washington that China could harness US AI capabilities to supercharge its military.
The most advanced chip Nvidia is currently allowed to sell to China is the H20, which is based off the company's older Hopper architecture platform. The Trump administration green-lighted exports of H20 AI to China last month.
The Trump administration last week also confirmed an unprecedented deal with Nvidia and AMD to give the US government 15 per cent of revenue from sales of some advanced chips in China.
China's renewed guidance on avoiding chips also impacts AI accelerators from Advanced Micro Devices, the Bloomberg report said, adding that it was unclear whether any notices from Chinese authorities specifically mentioned AMD's MI308 chip.

Poland's President Nawrocki takes part in Trump call, instead of rival Tusk

REUTERS/Aleksandra Szmigiel/File Photo WARSAW - Polish President Karol Nawrocki took part in a teleconference on Ukraine with U.S. President Donald Trump and European leaders on Wednesday, his office said, a call his bitter political rival Prime Minister Donald Tusk had been expected to attend. Nawrocki, a conservative nationalist and eurosceptic, is an ally of Trump's MAGA movement and visited the White House during Poland's presidential election campaign this year. He defeated the candidate of Tusk's party in a run-off vote. A government spokesperson had said on Tuesday that Tusk, a former head of the European Council of leaders, would attend the call with Trump. "Karol Nawrocki was invited to the talks with President Trump and other leaders of European countries," his foreign policy adviser Marcin Przydacz told reporters. "I have no information that Prime Minister Donald Tusk had previously planned to participate." He said the fact that Tusk's team thought he would take part showed they did not have good contacts with the Trump administration. Government spokesman Adam Szlapka said Tusk was representing Poland in two separate calls taking place on Wednesday and involving European leaders but not Trump. Przydacz said that president's and prime minister's offices would exchange information about the meetings. European leaders and Ukrainian President Volodymyr Zelenskiy spoke to Trump during a day of frenetic diplomacy ahead of the U.S. president's summit with his Russian counterpart Vladimir Putin in Alaska on Friday, stressing the need to protect Kyiv's interests.
