Kim Jong-un’s sister casts doubt on Trump’s claims of secret US-North Korea talks

President says he plans to meet dictator this year but Kim Yo-jong says Washington remains Pyongyang's enemy

Donald Trump has said he is planning to meet North Korea's Kim Jong-un later this year, though the reclusive leader's younger sister cast doubt on their communications and dampened hopes of a diplomatic breakthrough between them.

Trump, who also claimed North Korea had 57 nuclear weapons, had suggested he and Kim were holding secret negotiations on Tuesday after announcing the US would downgrade its participation in military exercises held by South Korea, a US ally. Asked whether Kim had responded to his request for a conversation, Trump said: Yeah, he has."
