On Monday, the US government announced a new round of regulations on global AI chip exports, dividing the world into roughly three tiers of access. The rules create quotas for about 120 countries and allow unrestricted access for 18 close US allies while maintaining existing bans on China, Russia, Iran, and North Korea.

The new rules build on previous chip controls from September 2022 and October 2023. The regulations will take effect in 120 days, extending into the incoming Trump administration.
