North Korean leader Kim Jong Un expressed an interest in visiting South Korea at a historic summit Friday with his South Korean counterpart Moon Jae-in. The two leaders are taking a lunch break before resuming their talks.

Earlier Friday, the North and South Korean leaders exchanged a warm handshake over the demarcation line that divides the two countries before the beginning of the summit.

North Korea’s Kim Jong Un then crossed the border with Moon Jae-in, the president of South Korea.

“I am happy to meet you,” Moon said.

Kim then invited Moon to cross briefly north with him before they returned to the southern side.

It is the first time a member of the Kim dynasty has set foot on southern soil since the end of the Korean War in 1953 in the latest bid to settle the world’s last Cold War standoff.

This will be the third inter-Korean summit — the summits in 2000 and 2007 were held in North Korea.

The White House released a statement late Thursday, shortly after the two leaders shook hands.
