US President Donald Trump confirmed on Friday that his much-anticipated summit with North Korean leader Kim Jong Un will go ahead as planned in Singapore on June 12. Trump made the announcement, just a week after he canceled the summit, after an hour-long meeting with a top North Korean official who delivered a letter from the North Korean leader. "I think its probably going to be a very successful, ultimately a successful process," Trump told reporters on the White House lawn. Kim Yong Chol, a close aide to the North Korean leader, was the highest level figure from the secretive state to hold talks at the White House since a senior envoy visited former President Bill Clinton in 2000. After exchanging threats and insults since Trump became president last year, the United States and North Korea have been trying to set up the summit between their leaders. Trump wants to sure the meeting to pressure Pyongyang into giving up its nuclear weapons. "Were going to deal," Trump told reporters. He also said it was likely that more than one meeting would be necessary. He concluded, "I think youre going to have a very positive result in the end. We will see what we will see." Trump added that he had not read the letter yet and added with a smile, "I may be in for a big surprise, folks." Plans for the high-stakes sit-down have been have been cast in doubt ever since Trump withdrew from the meeting last week, only to announce a day later that it could still get back on track. White House officials cast the roller-coaster public statements as reflective of the hard-nosed negotiation by the two nations. Three teams of officials in the US, Singapore, and the Korean demilitarized zone have been meeting this week on preparations for the summit. Questions remain about what a deal on the Norths nuclear weapons would look like though Trump said Friday he believed that Kim would agree to denuclearization. Despite Kims apparent eagerness for a summit with Trump, there are lingering doubts about whether he will fully relinquish his nuclear weapons, which he may see as his only guarantee of survival. US defense and intelligence officials have repeatedly assessed the North to be on the threshold of having the capability to strike anywhere in the continental US with a nuclear-tipped missile — a capacity that Trump and other US officials have said they would not tolerate.
