"We are only at the starting line," Moon told political party leaders after his envoys revealed Kim Jong Un's offer following their return from a historic trip to Pyongyang.

He denied allegations of a behind-the-scenes agreement with Pyongyang in return for it coming to the negotiating table.

"There has been no backroom deal whatsoever with the North," Moon was quoted as saying by a spokesman of the minor opposition Bareunmirae Party.

"There will be no such a thing as a gift to the North," Moon added.

The South's leader stressed the importance of maintaining close co-operation with the US, its security guarantor, adding: "I think denuclearisation talks will become feasible only when South Korea and the US take common positions" on the issue.

There would be no let-up in sanctions or pressure purely as a result of inter-Korean dialogue, he said.

 

"Inter-Korean talks won't be enough to achieve peace."
