South Korea’s minister of unification is holding out hope that North Korea will keep military tensions low in the coming weeks and keep diplomatic doors open.

On Friday, Lee In-young told South Korea’s Christian Broadcasting System (CBS) radio that there is a “low possibility” that North Korea will create military tension ahead of South Korean President Moon Jae-in’s visit to Washington on May 21.

“North Korea knows very well that military tension has turned things awry during the Obama administration,” he said. “It will not repeat mistakes like that again.”

Moon is expected to meet with U.S. President Joe Biden
