The Moon administration has submitted a motion to parliament that would have the legislature ratify the Panmunjom Declaration and make it law.
The government wants it passed ahead of next week's inter-Korean summit.
The motion, sent Tuesday by the Unification Ministry, is aimed at enhancing cross-border cooperation and exchanges, and pursuing the Korean Peninsula's "complete denuclearization."
It also included an estimate for the cost of implementing part of the agreement next year, which amounts to more than 2-hundred-60 million U.S. dollars.
The cost includes the estimated outlays for inter-Korean cooperation on railways, roads and forestry.
