North Korean leader Kim Jong Un invited South Korean President Moon Jae-in to meet in Pyongyang, a dramatic gesture that may raise prospects for easing tensions on the Korean Peninsula.

The invitation was verbally delivered by Kim’s sister, Kim Yo Jong, during a Saturday meeting at Moon’s presidential compound in Seoul a day after the opening ceremony for the Winter Olympics in South Korea. A Moon-Kim summit would mark the first time leaders of two countries have met in 11 years.

Moon’s office provided conflicting accounts of whether he would go to Pyongyang. A Blue House official initially said the president had accepted Kim’s offer, but that was later denied by chief spokesman Yoon Young-chan.
