South Korea calls for more impromptu talks with North Korea as U.S. prepares for summit

South Korea’s President Moon Jae-in said on Monday there could be more impromptu talks and summits with North Korea’s Kim Jong Un, as U.S. officials prepare for a historic meeting between President Donald Trump and Kim.

Moon and Kim Jong Un held a surprise meeting on Saturday at the border village of Panmunjom, during which they agreed that a North Korea-U.S. summit must be held.

“What’s more important than anything from the latest inter-Korean summit was that the leaders easily got in contact, easily made an appointment and easily met to discuss urgent matters, without complicated procedures and formalities, just like a casual meeting,” Moon told a meeting with senior secretaries.

Trump last week pulled out of the meeting with Kim, planned for June 12 in Singapore, before announcing he had reconsidered and American and North Korean officials were meeting to work out details.

On Sunday, the U.S. State Department said U.S. and North Korean officials had met at Panmunjom, a village in the Demilitarized Zone (DMZ) that runs along the heavily armed border between North and South Korea.

A “pre-advance” team of U.S. officials was also travelling to Singapore to meet with North Koreans there, the White House said.

Asian stocks and U.S. share futures gained on Monday, while shares in South Korean construction and railway firms surged after Trump said his officials and North Korea have resumed talks to prepare for the summit in June.

Shares of Shinwon Corp, which used to operate factories in the Kaesong industrial region near the Demilitarized Zone, jumped 22 percent, while Hyundai Engineering & Construction gained 24 percent.
