President Trump deserves “big credit” for kicking off the first talks between Pyongyang and Seoul in more than two years, South Korean President Moon Jae-in said Wednesday.

North Korea agreed Tuesday to send a delegation to next month’s Winter Olympics, which are set to begin next month in Pyeongchang, South Korea. The rival nations’ talks are the first sign of a possible thaw in their relationship.

The talks were held for the first time since 2015 and Moon credited Trump for sparking them, according to Reuters.
