The Globe and Mail reports in its Wednesday edition that President Donald Trump's announcement allowing Nvidia to sell semiconductors to China reversed years of policies designed to block China's access to advanced technologies. A New York Times dispatch to The Globe reports that officials in Washington argue that cutting off China from American technology is crucial to keeping the U.S. lead in artificial intelligence and slowing China's military and economic advancements. Nvidia head Jensen Huang spent months persuading Mr. Trump to reverse his decision, arguing that limiting China's access to U.S. technology only accelerates Chinese companies' improvements. Mr. Trump's decision to permit Nvidia to sell its H200 chip to vetted Chinese commercial customers strikes "a thoughtful balance that is great for America," according to a Nvidia spokesman. Mr. Trump's decision's impact is unclear, but China has invested billions to become an AI superpower. Chinese chipmakers are racing to develop advanced chips independently, while AI companies are enhancing their efficiency with available chips. Investor bets that a Chinese company could soon compete with Nvidia have driven huge gains in the country's tech stocks this year.
