The Biden administration has implemented new regulations controlling the international distribution of A.I. chips and models. These rules categorize countries into three groups: unrestricted access for the U.S. and 18 allies, a continued ban for nations under U.S. arms embargoes like China and Russia, and imposed limits for the rest of the world. These measures aim to maintain control over this powerful technology and prevent adversaries from utilizing it against the United States. However, tech companies express concern that these restrictions could hinder their global sales and growth potential.
