WHITE HOUSE — U.S. President Donald Trump on Friday met for 80 minutes in the Oval Office with a general he described as the second most powerful man in North Korea.
Afterward, Trump told reporters on the White House South Lawn that the June 12 summit in Singapore between him and North Korea's leader, Kim Jong Un, was back on.
Trump, however, sought to quell some of the high expectations, saying the summit would "be a beginning" and subsequent discussions were likely to be needed to get Pyongyang to agree to denuclearization.
"We're not going to go in and sign something on June 12th, and we never were," he said. "We're going to start a process."
Trump declared he "never said it happens in one meeting," but that it "will ultimately be a successful process."
Asked by VOA News whether the North Koreans had committed to complete, verifiable and irreversible denuclearization, Trump replied only that "we talked about a lot of things."
'Take your time'
The president said he told Kim Yong Chol, the former head of North Korean military intelligence, "Take your time. We can go fast. We can go slowly."
The president made clear that sanctions on North Korea would not be lifted, however, until the country agreed to give up its nuclear arsenal.
As the negotiations over the Singapore summit play out in public, there is a sense among some observers that Trump and Kim Jong Un each have a clear sense of the deal they ultimately want to strike.
Less clear is whether the U.S. and North Korean visions can match up in any meaningful way.
"Singapore might be the first time people will have to put their cards on the table," a U.S. official said on the condition of anonymity.
Upon his arrival Friday at the White House, Kim Yong Chol, who is under U.S. sanctions for links to cyberattacks against American companies, delivered a letter from Kim Jong Un.
While Trump did not reveal the contents, he described the gesture as "very nice."
