The Obama administration has responded to increasing Russian aggression by stepping up its own efforts to inflict economic pain on Moscow and isolate it diplomatically. The United States and the European Union announced a new round of sanctions on July 29 that bar a number of Russian banks from U.S. and European capital markets, deny Russian energy companies sophisticated oil development technologies, and expand restrictions on Russian defense technology.
Even worse for Moscow, the new measures make it harder for Russian companies to raise medium- and long-term financing in Western markets, and extract oil from the Arctic and new deep water and shale reserves. They also hurt the Russian economy by increasing investor anxiety, which is likely to accelerate capital flight and cause foreign bankers to cut back on loans to Russia.
After announcing the latest sanctions, U.S. diplomats traveled to China, Japan, Singapore, and South Korea to urge their Asian partners to support efforts to tighten the economic vice on Russia.
