President Donald Trump has offered an invitation to North Korean leader Kim Jong Un to meet at the demilitarized zone (DMZ) as he is leaving Japan for South Korea this weekend.

The meeting, as the president said, is just to shake hands and say hello.

“I will be leaving Japan for South Korea (with President Moon). While there, if Chairman Kim of North Korea sees this, I would meet him at the Border/DMZ just to shake his hand and say Hello(?)!” he wrote in a tweet on Saturday morning.

President Trump is scheduled to arrive in Seoul later on Saturday, June 29, after attending the G-20 Summit in Osaka, Japan. He is due to return to Washington on Sunday.

Before leaving the White House for Asia, President Trump told reporters he would meet a lot of leaders in Asia, and may speak to Kim “in a different form,” according to The Associated Press.

President Trump attempted to visit the DMZ in November 2017 with South Korean President Moon Jae-in, but the trip was canceled due to heavy fog.

The tensions between the United States and North Korea have been eased following two summits between President Trump and Chairman Kim, with the first in June 2018 in Singapore and the second in February 2019 in Vietnam. North Korea has not conducted any big nuclear or ballistic missile tests since then, though no deals have been signed.

Reuters citing South Korea’s Foreign Ministry reported U.S. Special Envoy Stephen Biegun said Friday that the United States was ready to hold constructive talks with North Korea to follow through on a denuclearization agreement reached at a summit between President Trump and Kim in Singapore last year.
