Export controls need to be tightened after revelations the Chinese company used Nvidia technology, the leaders of a congressional committee said.

Republican John Moolenaar and Democrat Raja Krishnamoorthi, who lead the House Select Committee on China, asked for the move as part of a Commerce and State Department-led review ordered by President Donald Trump to scrutinize the U.S. export control system in light of "developments involving strategic adversaries."

Trump administration officials are exploring additional curbs on the sale of Nvidia Corp. chips to China, according to people familiar with the matter, who emphasized that conversations are in very early stages as the new team works through policy priorities.
