President Donald Trump walks with South Korea's President Moon Jae-in at the White House in Washington, U.S., April 11, 2019.

President Donald Trump will meet with Moon Jae-in, the president of South Korea, as part of his travel to Asia for the G-20 summit of world leaders in Japan in late June, the White House said Wednesday.

The two will meet in South Korea to discuss efforts to rid the country's northern neighbor of its nuclear program, one of Trump's signature foreign policy priorities, press secretary Sarah Huckabee Sanders said in a statement.

Trump and Moon met last month at the White House. Trump said at the time he was still seeking to make a "big deal" with North Korea, but noted that there may be smaller deals made along the way.

"The big deal is we have to get rid of the nuclear weapons," Trump said.

That effort has shown little signs of progress since a historic summit between Trump and North Korean leader Kim Jong Un a year ago failed to bring about a detailed agreement. Trump cut short a second summit, hosted by Vietnam in February, after Kim called for the removal of all U.S. sanctions.

The announcement that Trump will meet Moon comes as tension between the U.S. and North Korea escalates.

On Tuesday, the rogue nation demanded the return of a cargo ship the United States seized for alleged sanctions violations.

And on Thursday, the president said that "nobody's happy" after the Pentagon reported ballistic missile launches in the country, the second set of launches in a week.

"They're talking about negotiating, but I don't think they're ready to negotiate," he said.
