US President Donald Trump said on Thursday it may take more than one meeting with North Korean leader Kim Jong Un to seal a denuclearization deal and that he would like Pyongyang to dismantle its nuclear weapons program as quickly as possible under any agreement, Reuters reported.

Trump, in a brief interview with Reuters aboard Air Force One as he flew to Texas for Republican fund raising events, said he was still hoping for a summit with Kim on June 12 in Singapore.

“I’d like to see it done in one meeting. But oftentimes that’s not the way deals work,” Trump said.
