Main opposition People Power Party(PPP) presidential candidate Yoon Suk Yeol pledged to normalize combined military exercises with the U.S. that were reduced in scale in a bid to spur denuclearization diplomacy with North Korea.

In announcing his North Korea, foreign affairs and defense policy pledges on Monday, Yoon said he intends to seek all available means to block the North's nuclear and missile threats to achieve peace through power.

Yoon plans to operate the Extended Deterrence Strategy and Consultation Group(EDSCG) with the U.S., reinforce the allies' extended nuclear deterrence, and secure Seoul's "Kill Chain" system for a preemptive strike against the North's threats.

On North Korea diplomacy, Yoon said he will establish a liaison office for the two Koreas and the U.S. either at the truce village of Panmunjeom or in Washington.

While international sanctions on the regime will remain until its complete denuclearization, some economic aid through the United Nations' sanctions exemption procedures will be allowed in return for steps toward denuclearization.
