President Donald Trump on Sunday became the first sitting American president to set foot inside the country of North Korea.

Trump shook hands with North Korean leader Kim Jong-un as he “crossed the low stone curb separating the North and the South at about 3:45 p.m. local time,” as Fox News and other outlets noted.

The two men also spent roughly 50 minutes meeting behind closed doors.

Trump told reporters after the meeting this weekend that the two leaders had agreed to revive talks on North Korea’s nuclear program.

“Speed is not the object” in trying to reach a deal, he said, but noted he believes both sides “want to get the job done.”

“We’re looking to get it right.”

Sanctions are still currently in place against North Korea.

The U.S. has said North Korea must submit to “complete, verifiable and irreversible denuclearization” before those sanctions can be lifted.
