The Kremlin is threatening Washington, D.C., with reciprocal measures after the U.S. added more Russian firms to its sanctions list. The White House expanded restrictions already put in place in response to Moscow’s annexation of Ukraine’s Crimean peninsula and its ongoing war against Ukraine.According to documents published by the U.S. Federal Register on Sept. 7, 81 more entities are now blacklisted, among them 11 from the Russian arms sector and 51 companies owned or operated by Russian gas monopoly Gazprom. The new additions to the sanctions list are described in the documents as “acting contrary to the national security or foreign policy interests of the United States.”

A Kremlin spokesman has said the latest sanctions are “not consistent” with talks recently held between Russian President Vladimir Putin and U.S. President Barack Obama. Dmitry Peskov revealed the two leaders discussed “possible cooperation in sensitive areas” when they met at a recent G20 summit in China. He has warned that Moscow will review the new blacklist and base its response on the principal of reciprocity.
