The change came a week after North Korean leader Kim Jong-un told South Korean President Moon Jae-in that he wanted to unify the time zones to promote inter-Korean reconciliation and unity, reports Yonhap News Agency.
The meeting is to ascertain the progress made ahead of a planned meeting between Trump and North Korean leader Kim Jong Un. "Denuclearization will be a great thing for World, but also for North Korea", Trump tweeted.
The meeting - expected to be held in late May or early June - would be the first between a sitting American president and the leader of North Korea.
Trump, speaking at the annual National Rifle Association in Dallas on Friday, says it was his "position of strength" that is bringing Pyongyang to the negotiating table. The government has taken criticism for putting North Korea's numerous human rights violations on the back burner in pursuit of peace and whatever that might include.
On Saturday the North's state media hailed the inter-Korea summit as a "historic meeting", adding that Kim and Moon "confirmed the common goal of realising, through complete denuclearisation, a nuclear-free Korean Peninsula".
Sensing the impact that the NYT report could have on the proceedings, both the USA and South Korea objected to it saying it was untrue.
National security adviser John Bolton called that report, in The New York Times, "utter nonsense" in a statement Friday.
'Now, I have to tell you, at some point into the future, I would like to save the money, ' Trump told reporters.
Xi laid emphasis on the bilateral ties, saying that Beijing is willing to boost the relationship between the two countries by enhancing communication with South Korea, deepening pragmatic cooperation, and promoting cultural exchanges.
According to the Yonhap news agency, the incident occurred in the town of Paju near the border with North Korea.
Trump told the National Rifle Association's annual convention in Dallas on Friday that he had toned down his rhetoric in anticipation of the talks after labelling Kim "Little Rocket Man" a year ago and threatening him with 'fire and fury'. 'Now I'm trying to calm it down a little bit'. In March, Washington and Seoul began negotiations on how much South Korea should offset the costs of the deployment in the coming years. They also will discuss the US president's own upcoming summit with the North Korean leader, a White House statement said.
