In a stunning move employing the Twitter diplomacy that he has become famous for, U.S. President Donald Trump on Saturday invited North Korean leader Kim Jong Un to meet him at the border between the two Koreas over the weekend — a proposal the regime in Pyongyang called "interesting."

"After some very important meetings, including my meeting with President Xi of China, I will be leaving Japan for South Korea (with President Moon)," Trump tweeted in the morning. "While there, if Chairman Kim of North Korea sees this, I would meet him at the Border/DMZ just to shake his hand and say Hello(?)!"

Trump's invitation for what would be a third meeting came during the final day of the Group of 20 leaders summit in Osaka, where he met with Chinese President Xi Jinping and South Korean leader Moon Jae-in.
