Kim Yo Jong has been described as a mouthpiece for her brother, North Korean leader Kim Jong Un — and a potential successor.

The country appeared to signal an openness to talks, but said it must be recognized as a nuclear power and would not discuss abandoning its arsenal.

New talks between North Korea and the United States are possible if Washington drops its demand that Pyongyang rid itself of nuclear weapons, Kim Jong Un’s powerful sister suggested in a statement released by state media Tuesday.
