Kim Jong Un’s sister heads home

North Korean leader Kim Jong Un’s sister headed home Sunday night after a whirlwind three days in South Korea, where she sat among world dignitaries at the Olympics and tossed a diplomatic offer to the South aimed at ending seven decades of hostility.

Kim Yo Jong and the rest of the North Korean delegation departed for Pyongyang on her brother’s private jet, a day after they delivered his hopes for a summit with South Korean President Moon Jae-in during a lunch at Seoul’s presidential palace.

It was a sharp, but possibly fleeting, contrast with many months of rising tensions connected to the North’s continued development of nuclear weapons and long-range missiles.

They capped their final day in South Korea by joining Moon at a Seoul concert given by a visiting North Korean art troupe led by the head of the immensely popular Moranbong Band, whose young female members are hand-picked by Kim Jong Un.
