US "deliberately provoke" North Korea before the historic summit between American and North Korean leaders Donald trump and Kim Jong-UN. "What we need is only peace", Moon recently told a group of South Korean officials.
But Graham, a former British diplomat who served in Pyongyang, noted that "Trump is clearly curious to see North Korea up-close".
The Trump and Kim Jong Un meeting has been confirmed and a date set - though which date? - we don't know yet.
The South's Yonhap news agency carried a similar report.
The United States claims President Trump's political pressures and sanctions are what encouraged North Korea to agree to a negotiation. The White House is also hoping that if North Korea releases the three Americans arrested before the meeting, this will calm the atmosphere and be a good start to the summit.
The USB was presented to Kim after he crossed the heavily guarded DMZ into South Korea by Moon Jae-in last month for the leaders' historic meeting at the border village of Panmunjom.
In the article, an unnamed foreign ministry spokesperson said the Trump administration "is deliberately provoking the DPRK" at the time when peace and reconciliation are being promoted in the wake of the inter-Korean summit.
Just a day after the inter-Korean summit, Moon spoke over the phone with Trump for one hour and 15 minutes. In addition, officials from the two countries have held already held talks several times there and Singapore has a history of hosting summits for leaders of other countries.
"This act can not be construed otherwise than a unsafe attempt to ruin the hardly-won atmosphere of dialogue and bring the situation back to square one", the statement read. The South Korean president said in January that Trump "deserves big credit for bringing about the inter-Korean talks".
Though the North had in the past sought withdrawal of USA troops stationed in South Korea as a condition to give up its nuclear weapons, it recently dropped the demand. "Now I'm trying to calm it down a little bit", he said.
The White House has said its pressure campaign on North Korea will continue until the North dismantles its nuclear program. Mr. Trump hinted the release of Kim Dong Chul, Kim Hak Song and Tony Kim was in the offing.
At that speech in MI, the crowd chanted "Nobel, Nobel, Nobel", possibly suggesting the president deserves the Nobel Peace Prize for his achievements.
He said the USB, which contained a plan for tens of billions worth of economic development in North Korea including railways and energy, sent the message to Kim: "We're serious about working with you for what we think is your real ambition - to be a wealthy East Asian country".
