US President Donald Trump proposed meeting with North Korean Supreme Leader Kim Jong-un at the demilitarized zone between North and South Korea, while speaking to the press during a meeting with Saudi Arabian Crown Prince Mohammad Bin Salman on the sidelines of the G20 meeting in Osaka on Saturday.

"I just put out, I just thought of it this morning, we'll be at the area, we may go to the DMZ, or the border, as they call it," Trump said, before commenting on how the demilitarised zone is a "real border" that "nobody goes through."

"So we'll be there and I just put out a feeler because I don't know where he (Kim) is right now. He may not be in North Korea, but I said if Chairman Kim would want to meet I would be at the border, and certainly we seem to get along very well, I can tell you. That's a good thing, not a bad thing," Trump continued.

Trump also praised the Saudi Arabian leader, calling him "a friend of mine" and described him as "a man who has really done things in the last five years in terms of opening up Saudi Arabia and I think especially what you've done for women, I am seeing what's happening, it's like a revolution in a very positive way."

Leaders of 19 of the most influential countries in the world and the European Union are meeting in Osaka on Friday and Saturday for the 14th Group of 20 summit to discuss climate change, free trade, and economic inequalities among other issues.
