At the SCM, the two sides are expected to reach an agreement on the suspension of their annual massive Vigilant Ace air exercise that involved some 270 aircraft last year in a show of force against a then-provocative Pyongyang.

Speculation has persisted that the exercise will be skipped to boost ongoing diplomacy with the communist regime.

Last week, the US Department of Defense said that the allies agreed to suspend the exercise. But Seoul's defense ministry said the allies just weighed "various ideas, including the suspension" in an apparent indication of differences over the fate of this year's exercise.

At the talks, the allies are also expected to finalize a provisional plan to reorganize a combined forces command after the transfer of wartime operational command, which will enable South Korea to lead combat operations with the U.S. playing a supporting role.

The SCM will be an opportunity for the allies to reaffirm that they are on the same page over ongoing peace efforts. Washington has reportedly been wary of the fast pace of inter-Korean exchanges at a time when Pyongyang has yet to take tangible denuclearization steps, such as a full declaration of its nuclear inventory.

Meanwhile, the defense ministry and the US Defense Department released a joint statement celebrating the 50th anniversary of the creation of the SCM.

"Over the past 50 years, the SCM has played a central role in maintaining peace and stability on the Korean Peninsula while reinforcing the ironclad ROK-US Alliance," the statement reads in English.

The statement also noted that the SCM and the alliance are taking on a greater importance than before as the security situations on the peninsula, the Asia-Pacific region and the world face a "turning point."

"Looking forward, the SCM will continue to seek ways to help bring complete denuclearization in a final, fully-verified manner and lasting peace to the Korean Peninsula," it added. (Yonhap)
