North Korea proposed to close down a portion of its Yongbyon nuclear complex in exchange for lifting of all U.N. sanctions except those directly targeting their weapons of mass destruction program, a senior U.S. State Department official said. 'The dilemma that we were confronted with is the North Koreans at this point are unwilling to impose a complete freeze on their weapons of mass destruction programs,' the official told reporters. 'So to give many, many billions of dollars in sanctions relief would in effect put us in a position of subsidizing the ongoing development of weapons of mass destruction in North Korea,' the official said. The official spoke to reporters following the collapse of a second summit between U.S. President Donald Trump and North Korean leader Kim Jong Un in Vietnam on Thursday
