When Kim Jong-un proposed participating in the 2018 Winter Olympics in South Korea in his New Year's address, the Seoul–Pyongyang hotline was reopened after almost two years. In February, North Korea sent an unprecedented high-level delegation to the Games, headed by Kim Yo-jong, sister of Kim Jong-un, and President Kim Yong-nam, which passed on an invitation to President Moon to visit the North. Kim Jong-un and Moon met at the Joint Security Area on 27 April, where they announced that their governments would work toward a denuclearized Korean Peninsula and formalize peace between North and South Korea. On 12 June, Kim met with Donald Trump at a summit in Singapore and signed a declaration, affirming the same commitment. Trump announced that he would halt military exercises with South Korea and foreshadowed withdrawing American troops entirely.
