This latest development has raised hopes for a revival of stalled nuclear talks, with Donald Trump expressing his wish to shake the North Korean leader’s hand in tweets posted yesterday.
The US president wrote: “After some very important meetings, including my meeting with President Xi of China, I will be leaving Japan for South Korea (with President Moon).
“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 is the first ever US president to visit the DMZ, the world’s last Cold War frontier.
The notorious region has seen a spate of dramatic diplomatic and military incidents over the years, as well as dozens of rounds of government, military and humanitarian talks since 1971, when the two Koreas opened their first hotline and liaison offices.
Most infamously, axe-wielding North Korean soldiers in the DMZ in 1976 murdered two American soldiers who were cutting down a poplar tree to secure a clear view.
