A statement on the U.S. treasury website said that, "The Strategic Force conducted multiple ballistic missile launches during 2014. Specifically, it conducted the launches of two short-range Scud-class ballistic missiles on March 3, test-fired two medium-range No Dong-class ballistic missiles on March 26, and conducted the launch of a short-range ballistic missile on July 26."

Previously sanctioned officials of North Korean banks were also blacklisted by the US Treasury. The Treasury has imposed sanctions on North Korea second time in four weeks. According to New York Times, the imposed sanctions reflect concerns about its efforts to improve the capabilities of weapons and missiles despite United Nations prohibitions.
