Hope Fading for Diplomatic Breakthrough to Denuclearize N. Korea Christy Lee WASHINGTON - Despite Washington's efforts to maintain a dialog with Pyongyang, chances for a diplomatic breakthrough leading to the denuclearization of North Korea are fading away, said experts, as the two nations remain locked in their position. "At some point, there needs to be a determination that diplomacy is yielding diminishing returns," said Robert Manning, a senior fellow at the Atlantic Council. After almost two years of diplomacy, North Korea has been repeating an ultimatum more frequently that the United States has until the end of this year to present a new proposal for denuclearization. As the Pyongyang-imposed deadline approaches, the regime has increased threats to change Washington's stance. Washington has been demanding North Korea conduct full denuclearization. Pyongyang wants the U.S. to relax sanctions and cease regularly held joint military exercises with South Korea, which it claims as a threat against its regime, before denuclearizing. Those positions have remained unchanged for months, despite the publicly affectionate relationship between North Korea's leader Kim Jong-un Kim and U.S. President Donald Trump. Christopher Ford, assistant secretary of state for International Security and Nonproliferation, said on Monday that the U.S. is still seeking "the final and fully verified denuclearization" of North Korea. On Tuesday, Ri Thae Song, North Korea's vice minister of Foreign Affairs, released a statement, reminding the U.S. that "drawing nearer is the year-end time limit the DPRK set for the U.S." to change its position. The DPRK stands for North Korea's official English name, the Democratic People's Republic of Korea. Song said, "The U.S. is keen on earning time needed for it, talking about the 'sustained and substantial dialogue,'" but "far from acting in response to the measures taken by the DPRK first." He continued, "What is left to be done now is the U.S. option and it is entirely up to the U.S. what Christmas gift it will select to get," presumably referring to more missile tests. The statement follows a test of two projectiles North Korea conducted on Thanksgiving Thursday. Pyongyang's official Korean Central News Agency (KCNA) said on Friday it tested a "super large multiple rocket launcher." It is North Korea's 13th missile test since May.
