China launches antitrust probe into AI chipmaker Nvidia

China's antitrust authorities announced the opening of an investigation into Nvidia over a possible breach of a deal struck back in 2020. The move is part of a wider US-China confrontation regarding chip technology which can power artificial intelligence systems, military equipment and cyber warfare infrastructure. Washington had ramped up its export controls on chip technology to China last week, placing 140 Chinese entities on a trade blacklist.
