On April 26, 2023, in recognition of the 70th anniversary of the U.S.-Korea alliance, President Joe Biden will host President Yoon Suk Yeol for a State Visit to the United States. According to Ambassador Jung-Seung Shin, the fact that Yoon received the second such invitation of the Biden administration is a testimony to the centrality of the Korea-U.S. alliance to the peace and stability of the East Asian regions, especially at a time when the frayed U.S.-China relationship continues to degrade into a new Cold War, with a potential Taiwan contingency looming on the horizon.
Shin, former South Korea's ambassador to China and former director general of the Asia Pacific Affairs Bureau at the South Korean Ministry of Foreign Affairs and Trade, is the Winter 2023 Payne Distinguished Fellow at the Freeman Spogli Institute for International Studies (FSI) and a visiting scholar at APARC. He headlined this quarter’s Payne Lecture, speaking to an audience that gathered on March 1 for a timely discussion titled Sino-U.S. Relations and South Korea, co-hosted by APARC and FSI.
The Payne Lectureship at FSI, named for Frank E. Payne and Arthur W. Payne, aims to raise public understanding of the complex policy issues facing the global community and advance international cooperation. The lectureship brings to Stanford internationally esteemed leaders from academia and the policy world who combine visionary thinking and a broad, practical grasp of their fields with the capacity to provide insights into pressing challenges of global concern. Throughout the 2022-23 academic year, the Payne Lectureship hosts experts from Asia who examine crucial questions in U.S.-China relations.
Ambassador Shin is uniquely qualified to offer insight into South Korea's response to the pressures created by the U.S.-China rivalry, said APARC Director Gi-Wook Shin, who chaired the event that included a discussion with Center Fellow Oriana Skylar Mastro, an expert on Chinese military and Asia security.
Painting a picture of Chinese ambitions, Ambassador Shin enumerated China’s goals and the steps it has taken to achieve them. “The Chinese dream,” he said, “is to regain the colonial behavior of the Qing Dynasty, when China was a great power with about one-third of the global GDP.” To achieve this dream, China's leaders have pushed for its continued economic development while arousing patriotism and nationalism domestically. Through its military modernization campaign, China has rapidly shown its ambition to become the top-rated global military power by 2049, the centennial of the establishment of the People's Republic of China, he noted.
Ambassador Shin indicated that China has prepared for a long-term competition with the U.S. in the economic arena, as Xi Jinping introduced the dual circulation economic policy, which aims to reorient the country's economy by prioritizing domestic consumption while remaining open to international trade and investment. This policy, Shin argues, “is designed, in part, to make the [Chinese] economy less affected by external factors including the supply chain reset of the U.S.” As such, China has stressed the importance of innovation and has made massive investments in science and technology to reduce its reliance on Western economies. Moreover, China has promoted the Belt and Road Initiative (BRI) to expand its political and economic influence.
“China became the second largest economic power and began to show assertiveness in its foreign policy, particularly by emphasizing the safeguarding of Chinese interests, namely, sovereignty and territorial integrity, state security and development interest,” stated Shin. To achieve these goals, “Chinese diplomats have voiced their arguments in an abrasive style, ‘Wolf Warrior diplomacy’ as it is called by Westerners.” This form of proactive engagement with the rest of the world has resulted in an intensifying strategic competition between the U.S. and China, which has made it increasingly difficult for South Korea to maintain simultaneous ties with both great powers.
No Longer on the Fence
Shin noted that “The strategic distrust and intensifying rivalry between the U.S. and China have put substantial pressure on South Korea…and South Korea's long-term policy to make a Korea-U.S. alliance compatible with its partnership with China is becoming more difficult.” In recent years, South Korea has moved even closer to the U.S.
The joint communique issued when President Moon Jae-in visited Washington two years ago, already showed South Korea’s tilt toward the U.S. At the time, heightened tensions on the Korean peninsula by the North Korean nuclear and missile provocation necessitated the alliance. Now, an ascendant China, “together with the lessons of Ukraine, have made South Korean people pay close attention to the importance of the Korea-U.S. alliance,” stated Shin, noting that both nations openly stress the importance of freedom, democracy, and rule-based order. South Korea has become enthusiastic about tripartite cooperation among South Korea, the U.S., and Japan, in tune with American policies.
On the other hand, China warned South Korea to respect China's core interests while expressing its concerns on several strategic issues. Shin stated that “China began to demand the Yoon government to continue the three policy positions of the previous government, namely, no more deployment of Terminal High Altitude Area Defense (THAAD), no participation in the American missile defense system, and no military alliance among Korea, Japan, and the U.S.” However, the current Foreign Minister Park Jin made it clear to the Chinese Foreign Minister Wang that the policy positions of the previous government do not bind the new government, Shin indicated.
The Taiwan Contingency
Shin indicated the precarious nature of the contingency, stating, “South Korea has no intention of challenging the One China claim. However, the peace and stability of Taiwan Strait are also very important for South Korea, as the security situation of the Taiwan Strait is connected to the Korean peninsula.” Indeed, a military collision in the Taiwan Strait would be impossible to contain locally. “The U.S. and Japan are supposed to immediately help Taiwan to repel China’s military attack, and American bases are located in South Korea and Japan, including Okinawa,” he said.
Therefore, military conflict in the Taiwan Strait is likely to escalate to Northeast Asia, and a certain portion of American forces in South Korea could move to the Taiwan Strait in the contingency according to the strategic flexibility of forces, “which might induce North Korea's misjudgment to invade South Korea,” Shin predicted.
Looking to National Identity
The Cost of Deterrence
Overextension represents one of the largest limits on U.S. power projection. According to Mastro, one of the primary reasons that the Biden administration has not been talking about North Korea significantly, is the fact that the U.S. cannot fight a war on the Korean Peninsula and compete effectively with China.
Thus, Mastro proposes that the South Koreans play a greater role in their defense, a topic that comes up with NATO partners and allies in Europe as well. More specifically, Mastro suggests that the U.S. transfer operational command to South Korean forces, and that the South Korean military should allow the U.S. to practice greater strategic flexibility, to use its forces on the Korean Peninsula for operations or contingencies that are off the peninsula. Up until this point, that permission has been denied, but Mastro contends that it would be useful and could enhance deterrence.
“If the South Koreans, along with their statements about wanting a Free and Open Indo-Pacific, also explicitly allowed for that strategic flexibility to take place to say that they understand that the role of U.S. forces on the Korean peninsula is primarily to deter and defend South Korea against North Korea, that could also play a potential role in wider contingencies,” she said.
Furthermore, Mastro believes that South Korea must play a greater role in the production and provision of certain types of munitions. “This is an area where the U.S. has struggled with its own manufacturing base that is considering licensing production and potentially doing it elsewhere. So the question is whether the U.S. could count on South Korea for some critical supplies during a conflict that could reduce the U.S. logistical burden,” she speculated.
South Korea is a small country, and it has limited resources, but it also has the second-largest reserve force and paramilitary force in the world, and the eighth-largest active duty force in the world. According to Mastro, “The South Korean military is technically 20 times larger than that of Japan's…it has punched above its own weight, like the Australian military has.”
It remains to be seen whether the U.S.-South Korea alliance will need to be tested in the coming years, but tensions with China will likely continue to define the two nation’s foreign policies. A potential Taiwan contingency remains one of the largest looming threats to the status quo and the most probable pathway to regional escalation, which, in Shin’s view, could draw North Korea and its nuclear arsenal into the fold.
The Payne Lectureship will return in the spring quarter, continuing with the theme of Asian perspectives on the U.S.-China relationship. We will be joined by Kokubun Ryosei, professor emeritus at Keio University and adjunct adviser at the Fujitsu Future Studies Center.
