The boss of Nvidia says he is “disappointed” that China has reportedly ordered its top technology companies to halt purchases of the firm’s artificial intelligence (AI) chips.
Jensen Huang told BBC News the US needs “to make sure that people can access this technology from all over the world, including China.”
He added: “The advance of human society is not a zero-sum game.”
Mr Huang is one of a number of tech bosses, including Microsoft’s Satya Nadella, accompanying US President Donald trump on his state visit to the UK.
“President Trump is very clear,” Mr Huang said. “He wants America to win, and President Xi wants China to win, and it’s possible for both of them to.”
But he believes “the conversation will sort itself out.”
Donald Trump is expected to speak to China’s President Xi Jinping on Friday.
Nvidia – the world’s leading chipmaker – had previously been banned from selling its most advanced chips to China, before Trump reversed the ban in July.
Nvidia has to pay 15% of its Chinese revenues to the US government in an unprecedented deal struck in the summer.
On Wednesday morning, the Financial Times reported that China’s Cyberspace Administration had told tech companies to stop using Nvidia chips which had specifically been manufactured for the Chinese market.
Shares of the US company were down more than 1% in premarket trading.
Mr Huang said he would “support the US” as they try to resolve geopolitical issues, and would tell the same thing to Trump if he is asked about it on Wednesday evening.
The UK is hosting Trump at a state banquet, where tech bosses including Mr Huang are expected to attend.
The US and China have been in trade talks in Europe this week.
On Monday, China’s market regulator said Nvidia had violated Chinese anti-monopoly laws, without giving any more details.
