The US is considering restricting the flow of semiconductors into Russia to deter Russian President Vladimir Putin from invading Ukraine. The move would prevent the Russian military and much of the nation’s economy from advancing technologically.

The details of the sanctions are still being decided, but they would rely on similar restrictions that kneecapped Huawei, the Chinese tech company. Though most semiconductors are made overseas, US companies control huge swaths of the larger market, from chip design and manufacturing equipment to process and quality control. By restricting access to those companies’ products and services, the US can effectively limit Russian access to the latest chips, even if they’re made in other countries.

“It’s one of the tools that US has come to prefer because it’s painful but it doesn’t involve the use of force,” James Andrew Lewis, senior vice president and director of the Strategic Technologies Program at the Center for Strategic and International Studies, told Ars. “It sort of freezes Russia at a technological moment.”
