Seoul and Pyongyang have agreed to hold a joint leader's summit at the Demilitarized Zone towards the end of April. The announcement comes after a South Korean delegation returned home after meeting with Kim Jong Un in Pyongyang. Meanwhile President Trump said on Twitter, that regardless of what happens, the US is ready to go hard in either direction. CGTN's Jack Barton has this report from Seoul.

After returning to Seoul the leader of South Korea's delegation to Pyongyang announced plans for a summit between D.P.R.K. leader Kim Jong-un and the South's President Moon Jae-in to be held at the demilitarized zone. It would be the third meeting ever held between leaders of the two Koreas.

CHUNG EUI-YONG HEAD OF SOUTH KOREAN DELEGATION AND NATIONAL SECURITY OFFICE "The two countries will hold the third summit at the Peace House in Panmunjom in late April. For this, we agreed to hold working level talks.

A hotline is also to be established between the two leaders so they can speak ahead of the summit about de-escalating tensions on the peninsula. Having expected to meet senior officials in Pyongyang, South Korea's special delegation instead found themselves wined and dined for more than four hours by non-other than D.P.R.K. leader Kim Jong-un and his wife. And it appeared President Donald Trump's preconditions for talks between Pyongyang and Washington had been met.

CHUNG EUI-YONG HEAD OF SOUTH KOREAN DELEGATION AND NATIONAL SECURITY OFFICE "North Korea made a clear case for denuclearisation on the Korean Peninsula and said that there was no need to keep its nuclear programme as long as there was no military threat against it and the safety of its regime was secured."

Though the breakthrough diplomacy does not mean there won't be trouble ahead.

JACK BARTON SEOUL "South Korean President Moon Jae-in has reiterated his call for deepening dialogue with the D.P.R.K. but also stressed the need to strengthen defence cooperation with the United States, saying peace cannot last without strong military power."

Large-scale war games between South Korea and the United States have been postponed until after the Winter Paralympics, though they are then scheduled to resume.

That could provoke a response from Kim Jong-un, who, according to the South's delegation, has promised not to test nuclear or conventional weapons as long as talks are continuing. Jack Barton, CGTN, Seoul.
