The Pentagon has raised concerns about China's access to artificial-intelligence-based technology developed in the US, according to Reuters. The news agency says a leaked report proposes that export controls be updated to stop Chinese organisations being able to invest in some start-ups. It suggests the move is needed to prevent their advanced algorithms being repurposed for the military by Beijing. One expert said the report sounded credible. "Quite a few people in the US security establishment see China as a likely potential adversary," Prof Trevor Taylor, from the UK's Royal United Services Institute for Defence and Security Studies, told the BBC.
