U.S. President Joe Biden’s administration is widening sanctions on the sale of semiconductor chips and other goods to Russia, targeting third-party sellers in China and elsewhere as it looks to further choke off Vladimir Putin’s war machine in Ukraine.

The Biden administration on Wednesday will announce changes that broaden the scope of existing export controls and restrictions to target U.S.-branded goods even if they’re not domestically made, according to people familiar with the move who requested anonymity to detail the plans before the announcement.

Chips, in particular, are a key target of the changes.
