Vietnam has emerged as the apparent front-runner for hosting a second summit between U.S. President Donald Trump and North Korean leader Kim Jong Un, after a second report cited the Southeast Asian country as a potential host city.

The U.S. side has proposed to the North holding the talks in Vietnam in mid-February, the Yomiuri Shimbun daily reported Sunday, citing unidentified sources, as expectations grow that a second summit could help break the stalemate in ongoing denuclearization negotiations.

The report said Pyongyang was reviewing the U.S. proposal and had yet to give a formal response.
