South Korea Envoys to U.S

Two South Korean envoys travelled to the United States yesterday to meet National Security Adviser H.R. McMaster and other officials to discuss this week’s meeting with North Korean leader Kim Jong Un, officials in Seoul and Washington said.

National Security Office head Chung Eui-yong and National Intelligence Service chief Suh Hoon will also speak with other department heads and later possibly meet either U.S. President Donald Trump or Vice President Mike Pence, a South Korean government official said on condition of anonymity.

The official said Chung had already spoken to McMaster on the phone shortly after completing this week’s visit to economically and diplomatically isolated North Korea.

The South Korean envoys were expected to brief U.S. officials on North Korea’s stance on possible future talks with Washington and its apparent willingness to suspend nuclear tests if the security of the North’s government is assured.

U.S. Defense Secretary Jim Mattis was guarded when asked on Wednesday about the prospect of North Korean engagement.

“Obviously we’re cautiously optimistic that there is some forward progress here,” Mattis told reporters at the Pentagon.

“But we’ve been optimistic before, so we’re going to have to watch actions and see if they match words,” he said.

Tensions over North Korea’s nuclear and missile programmes rose to the highest level in years in 2017. Pyongyang pursues its weapons programmes in defiance of U.N. Security Council resolutions, with shrill, bellicose rhetoric coming from both Kim and Trump.

North Korea has boasted of its plans to develop a nuclear-tipped missile capable of reaching the mainland United States. However, fears of all-out war eased last month, coinciding with North Korea’s participation in the Winter Olympics in the South.
