Are sanctions enough to deal with North Korea? (Paul Park, Katharine H.S. Moon, Brookings)

On February 18, President Barack Obama signed the North Korea Sanctions and Policy Enhancement Act (H.R. 757) into law in response to the North Korean (DPRK) nuclear test in January and rocket launch in February. The law strengthens U.S. sanctions against North Korea by making it mandatory, not just discretionary, for the president to designate violating entities for sanctions. It grants substantial tools for employing secondary sanctions by requiring the U.S. Treasury to determine if North Korea is a “primary money laundering concern.” North Korean minerals and metals exports are especially targeted as potential sources of revenue that would feed the nuclear and missile programs.
