South Korea's Moon Jae-in administration will soon begin official procedures associated with its plan for food aid to North Korea, a Cheong Wa Dae official said Wednesday.

The official, however, said it's still too early to talk in detail about the issue, as the government has yet to review the size, format and other specifics.

Moon and U.S. President discussed the humanitarian issue in their phone conversation Tuesday night (Seoul time).

"We are at a stage of beginning a review of all those matters," including preparations for domestic procedures, the official told reporters in a background briefing.

It has not been decided yet whether Moon will meet with the envoy in person, the official added. (Yonhap)
