The leaders signed a joint statement agreeing to firm security guarantees for North Korea, the complete denuclearisation of the Korean peninsula, and new peaceful relations between the reclusive state and the US.
However the US leader is reportedly growing impatient after North Korea canceled a series of high profile meetings with US officials, has neglected regular communication with the US administration, and has failed to provide guarantees on the nation’s commitment to denuclearisation.
Duyeon Kim, a North-Korean expert at the Centre for a New American Security, told the US newspaper: “Trump has been hit with a strong dose of reality of North Korea’s negotiating style, which is always hard for Americans to understand.
“I worry that Trump might lose patience with the length and complexities of negotiations that are common when dealing with North Korea, and was away and revert back to serious considerations of the military option.
“Getting a nuclear agreement takes a long time, and implementing it will be even harder.”
White House sources also revealed that US intelligence officers believe North Korea is attempting to conceal elements of its nuclear weapons program and production facilities.
Revelations of President Trump’s growing frustration come following conversations with six White House aides, diplomats and State Department officials, who remain anonymous.
President Trump has nevertheless publicly expressed his satisfaction with the ongoing negotiations.
Speaking to the media on Tuesday, the US leader said: “Discussions are ongoing and they’re going very well.”
He also noted he gained support from Russian President Vladimir Putin during their showdown meeting at the Helsinki summit.
Writing on Twitter, he said: “Russia has agreed to help with North Korea, where relationships with us are very good and the process is moving along.
“There is no rush, the sanctions remain!
“Big benefits and exciting future for North Korea at the end of the process.”
He however doubled down on previous claims the Singapore summit agreements would be implemented rapidly, signalling that the US administration may be obliged to wait for improvements to materialise in time.
Speaking to CBS regarding the denuclearisation process, President Trump said: “I’m in no real rush.
“I mean whatever it takes, it takes.”
Victor Cha, a North Korea expert, nevertheless signalled the US leader would not walk away from the agreement and breakthroughs reached in Singapore.
He said: “Trump is too vested to walk away right now. At least until after the midterms.”
