South Korea’s relationship with the U.S. as a protectorate has benefited Seoul strategically and economically. As tensions between China and the U.S. change the geopolitical climate of the region, South Korea may want to reevaluate the cost of a large U.S. military presence in their territory.

No leader of a U.S. ally has ever made such a show of fidelity before a trip to Washington. Yoon swiftly patched up relations with Japan, announced military aid to Ukraine and made comments on Taiwan.

Stronger U.S.-ROK ties have aggravated tensions with the DPRK, and the situation has deteriorated further since the ROK’s new president assumed office. In the North’s eyes, America’s maximum pressure approach excludes any possibility for meaningful dialogue.

The DPRK places Northeast Asia at risk, and their current military trajectory could pose problems for the PRC as well as the U.S. and its allies. So despite their fundamental differences, it’s in the best interests of both Washington and Beijing to find opportunities to cooperate to promote regional stability.

The United States and its allies are less interested in solving the problem than they are in containing China. But even if conflict is avoided, the intensification of a new cold war in Northeast Asia and the rising risk of nuclear proliferation do not bode well for the future.

Regional strategic stability depends upon sincere outreach to the DPRK by major powers. Think tanks from China, the U.S. and the ROK have already reached many useful common understandings. They should explore a road map for denuclearization and a peace mechanism and invited the DPRK to participate.

The U.S. and South Korea continue to look for ways to address the challenges with North Korea, while hoping for the involvement of China. Yet, China is unlikely to get involved unless its interests are also met in the process.

Heightened U.S. military deployments on the Korean Peninsula will only exacerbate the regional security dilemma that affects China, Russia and the DPRK. Meanwhile, exclusivity between the United States and ROK in some trade sectors will be hard to pull off.

South Korea is signaling a dramatic reorientation in its foreign policy, and it could become a key player in an expanded Quad platform.

As it grows stronger, South Korea naturally wants to play a bigger role in world affairs. But drawing close to the U.S. in all fields to elevate its importance will ultimately constrain its diplomatic space and flexibility.
