Chip Sanctions Challenge Russia's Tech Ambitions

An international tech blockade threatens to deprive Russia of sophisticated semiconductors needed to power advanced weaponry and cutting-edge technologies like 5G, artificial intelligence and robotics, experts say. In late February, the U.S. imposed a ban on selling high-tech products including semiconductors and telecommunications systems used by the defense, aerospace and maritime industries to Russia and its ally Belarus, days after Russia invaded Ukraine. The ban also extended to certain foreign items produced with U.S. equipment, software or blueprints.
