US vies with allies and industry to tighten China tech controls

The Biden administration is fighting to overcome opposition from allied nations and the tech industry as it prepares to expand restrictions aimed at slowing China’s ability to make the most advanced semiconductors, which could be used to bolster Beijing’s military capacity.

The administration has drafted new rules that would limit shipments to China of the machinery and software used to make chips from a number of countries if they are made with American parts or technology, as well as some types of semiconductors, according to people who have seen or were briefed on a draft version of the rules.
