Donald Trump and Kim Jong Un are set to choose Hanoi for their second face-to-face meeting, South Korean media reports. U.S. officials have already met North Korean counterparts in the Vietnamese capital to plan out the reunion, according to South Korean newspaper Munhwa Ilbo, which cited unnamed diplomatic sources in Seoul and Washington. Trump previously said he plans to hold a second meeting with Kim as early as this month—Singapore, Mongolia, and Switzerland have been named as possible locations for the meeting, as well as Vietnam. Denuclearization talks between the U.S. and North Korea have stalled since the two leaders met in Singapore last June. Kim piled pressure on Trump by threatening in his annual New Year’s address to take a “new path” if the U.S. didn’t relax its economic sanctions against his country. Mark Lambert, a senior U.S. State Department official handling North Korea issues, reportedly visited Vietnam in December—as did North Korean Foreign Minister Ri Yong Ho.
