Staff Correspondent: US President Donald Trump described his meeting with China's leader Xi Jinping was a "great success" and said he would head to China in April for new talks.

"I'll be going to China in April and he'll be coming here sometime after that, whether it's in Florida, Palm Beach or Washington, DC," Trump told reporters on Air Force One.

"A lot of things we brought to finalisation" at Thursday's talks in Busan, South Korea, added Trump, praising Xi as a "tremendous leader of a very powerful country".
