WATCH: Trump Becomes First Sitting US President to Set Foot in North Korea

U.S. President Donald Trump has become the first incumbent president in the history of the United States every to set foot in North Korea.

The president and North Korean leader Kim Jong-un were to meeting Sunday at the DMZ after agreeing to the impromptu summit late Saturday following a proposal by Trump during his remarks to media at a news conference in Osaka at the conclusion of the G20 gathering.

“We are trying to work it out,” he told reporters. “It will be very short but that’s okay. A handshake means a lot.”

On Sunday at around 2:40 am ET while Trump was waiting at the DMZ together with South Korea’s President Moon Jae-in, the two leaders spotted each other from across the divide, Fox News reported.

Each walked toward the other. They met, shook hands, and then together briefly walked across the border into North Korea, and then together walked back into the DMZ, together making history for both.

It was the third time the two men have met during Trump’s term in office.
