Trump says he knows how North Korea's Kim is doing

US President Donald Trump said on Monday he knows how Kim Jong Un is doing and hopes he is fine, after days of speculation over the North Korean leader's health.

"I can't tell you exactly," Trump said when asked about Kim's condition at a White House news conference. "Yes, I do have a very good idea, but I can't talk about it now. I just wish him well."

"I hope he's fine. I do know how he's doing relatively speaking. We will see - you'll probably be hearing in the not too distant future," Trump said.

In other news, China's foreign ministry said on Monday it has no information to offer regarding North Korean leader Kim Jong Un, amid conflicting reports and speculation about his whereabouts and medical condition.

Foreign ministry spokesman Geng Shuang made the comment during a daily briefing after being asked about reports of a Chinese delegation including medical experts being dispatched to North Korea, and whether they were sent to assist Kim Jong Un or help the country deal with Covid-19.

Three people familiar with the situation told Reuters that a Chinese team was dispatched to North Korea on Thursday to advise on Kim, though it was not clear what this mean about the North Korean leader's health.
