United States President Donald Trump on Tuesday mocked North Korean leader Kim Jong-Un and boasted that the US has a nuclear button which apparently "is much bigger and powerful" than what North Korea claims to have.

Trump's statement comes after Jong-Un's New Year message. "The entire United States is within range of our nuclear weapons, and a nuclear button is always on my desk. This is the reality, not a threat," Jong-Un had said.

Earlier, South Korea had offered a proposal of high-level talks with Pyongyang on January 9, to which North Korea did not respond. However, the proposal of talks between the North and South Korea has been dismissed by Nikki Haley, the US envoy to United Nations, after the US warned that Washington would never accept a nuclear-armed Pyongyang.

Haley said, "We won't take any of the talks seriously if they don't do something to ban all nuclear weapons in North Korea."

Meanwhile, Trump slammed his North Korean counterpart and said, "Soldiers are dangerously fleeing to South Korea. Rocket man now wants to talk to South Korea for first time. Perhaps that is good news, perhaps not — we will see!"
