The United States has imposed sanctions on Russian and Chinese companies, including Russian state-owned arms exporter Rosoboronexport, for violating a U.S. rule restricting trade with Iran, North Korea and Syria. The U.S. State Department published a notice of the sanctions in the Federal Register on Wednesday. They were later condemned by the Russian Foreign Ministry. Moscow will take countermeasures in response to new U.S. sanctions, Interfax reported late on Wednesday, citing a commentary on the Russian Foreign Ministry’s website. The State Department’s notice did not specify how each company had run afoul of the United States’ Iran, North Korea, and Syria Nonproliferation Act. The companies sanctioned also included China’s BST Technology and Trade Co as well as the Russian Aircraft Corp.
