The issue of providing North Korean residents with Tamiflu, an antiviral medication, has been also resolved, Lee told reporters.

The two Koreas plan to hold a groundbreaking ceremony in the North's border town of Kaesong on Wednesday for their work to modernize and re-connect cross-border roads and railways.

Seoul sought to head off a possible controversy over the ceremony, as Pyongyang is subject to a wide web of tough sanctions led by the US and the United Nations for its nuclear and missile program.

The allies also agreed that they face a crucial moment in the coming months for the complete denuclearization of the peninsula and establishment of a peace regime, he added.

In that sense, Lee said, the allies agreed to work together for early working-level talks between Pyongyang and Washington. (Yonhap)
