United States President Donald Trump has said there is a “very substantial chance” a historic summit with North Korea’s Kim Jong-un may not take place as planned on June 12 amid concerns that Kim is resistant to giving up his

nuclear weapons.

He said the North must meet conditions for the summit to go ahead though if it did not, it might happen “later”.

Trump raised doubts about the Singapore summit in talks with South Korean President Moon Jae-in, who came to Washington to urge Trump not to let a rare opportunity with reclusive North Korea slip away.

Meanwhile.. South Korean presidency Spokesperson said that the High-level talks between North and South Korea will likely resume after June 25 following completion of joint U.S.-South Korea military drills. He was speaking to reporters in Washington following a White House meeting between U.S. President Donald Trump and South Korean President Moon Jae-in.

North Korea last week cancelled at the last minute a meeting with senior South Korean officials in protest over joint exercises between Seoul and Washington and also threatened to scrap an unprecedented summit between Trump and North Korean leader Kim Jong Un.
