It will take more time for President Moon Jae-in to generate a visible outcome as a mediator and facilitator in the stalled denuclearization talks between Washington and Pyongyang as the United States is still unlikely to reach a possible "one-shot big deal" with North Korea in the foreseeable future, experts said, Friday.

They say the South Korean government needs to come up with a fresh way to resume the stalled nuclear talks at a time when the year-long mediating role has reached a deadlock and shows no signs of generating results in the short term.

Christopher Ford, assistant secretary for the U.S. Department of State, recently updated Washington's position of taking such an approach during the possibly upcoming talks with Pyongyang.

"It may be, moreover, that such a one-time solution set can sometimes be generated within the nonproliferation enterprise itself," he said in an address at the American Academy for Strategic Education.

The remarks conflict with the North's preferred stance of seeking to engage in incremental approaches having the United States in the nuclear disarmament talks. Pyongyang was hoping to get a limited sanctions relief from Washington in exchange for taking phased denuclearization steps. There were calls that Washington needs to take quite a flexible assessment in handling nuclear talks with the North.
