U.S. President Donald Trump on Saturday signaled willingness to go ahead with a June 12 summit with North Korean leader Kim Jong Un, saying talks between the two countries on the event are going "very well."

"We're looking at June 12 in Singapore. That hasn't changed," Trump said after Kim expressed his "fixed will" to have "historic" summit talks with Trump in Singapore, an event the U.S. leader abruptly cancelled Thursday but said the following day could still take place on the original date.

"I just want to mention we're doing very well in terms of the summit with North Korea. Looks like it's going along very well," he told reporters at the White House. "So we'll see what happens."

In preparation for a June 12 summit, a White House advance team is scheduled to depart Sunday for Singapore via Japan for a round of planning meetings with North Korean officials, according to a U.S. media report.

The advance team is set to arrive in Japan on Monday and will leave for Singapore the same day, Politico said, citing the manifest for the trip.

The team, involving about 30 White House and State Department officials, is led by White House deputy chief of staff Joe Hagin and special assistant to the president Patrick Clifton, it said.

Trump spoke after Kim on Saturday had a second meeting with South Korean President Moon Jae In at the truce village of Panmunjeom and expressed his commitment to the "complete denuclearization" of the Korean Peninsula.

"We can be successful in the denuclearization of the Korean Peninsula, that could be a great thing for North Korea, it would be a great thing for South Korea, it would be great for Japan, it would be great for the world, it would be great for the United States, it would be great for China," Trump said.
