South Korea and the South China Sea: A Domestic and International Balancing Act

Abstract

South has long been unclear on its stance regarding the territorial disputes in the South Sea. For many years, the closest thing the government had to an official position was the consistent but vague statements of successive spokespeople from the Ministry of Foreign Affairs. These statements essentially noted that the Republic of (ROK) supported freedom of navigation in the South Sea and hoped the parties involved would resolve the disputes in a peaceful manner through dialogue.In 2015, however, there was a slight but crucial change in that position. There had long been rumors that South was under pressure from the United States to clarify its position on the South Sea. Then, in November, Defense Minister Han Min-goo delivered remarks at the ASEAN Defense Ministers' Meeting-Plus (ADMM-Plus) stating that freedom of navigation and overflight must be guaranteed and that the disputes should be resolved in a peaceful manner.1 Later that month, President Park Geun-hye went a step further at the East Asia Summit in Malaysia when she stated that concerned parties should observe the Declaration on the Conduct of Parties in the South Sea and that disputes should be resolved according to international law. She went on to assert that concerned countries must respect the promise of demilitarizing the South Sea, which was widely interpreted as supporting the U.S. position on the disputes. At the 2015 East Asia Summit, Park argued that Korea has consistently stressed that the dispute must be peacefully resolved according to international agreements and code of conduct and China must guarantee the right of free navigation and flight. 2Despite these recent clarifications by the president and defense minister, South Korea's position on the disputes in the South Sea has been quite vague and ambivalent. While South does not claim any territories in the South Sea and has no direct military or strategic interests there, to fully understand the country's position, it is important to understand what stakes the ROK does have in the resolution of the current disputes. This essay examines these issues and draws implications for South Korea's relations with both the United States and China.South Korea's Economic and Diplomatic Interests in the South SeaThough lacking direct strategic and military interests in the region, South nevertheless has huge economic interests in the South Sea. As the world's sixth-largest trading nation by volume, it is highly dependent on the free flow of goods. In 2014, more than 1.1 billion tons of its trade passed through the South Sea. South is also highly dependent on energy resources from overseas. Approximately 86% of its oil consumption is supplied by imports from the Middle East, almost all of which must transit the South Sea.3 In sum, any undesirable events in the South Sea or a consequential blockade of its sea lanes would be devastating to the South Korean economy.The ROK's diplomatic interests in the region are just as important as trade. First, in recent years, South has developed a close partnership with the Association of Southeast Asia Nations (ASEAN) countries, and two of the most vocal South Sea claimants-the Philippines and Vietnam-are ASEAN members. South fears that when it discusses security cooperation with the ASEAN countries, its position on the disputes may be on the agenda, which is likely to put it in an awkward position. Additionally, South frequently calls on ASEAN countries for support on Korean Peninsula issues such as North Korean denuclearization. If some ASEAN countries were to ask it to support ASEAN's position on the South Sea disputes in return for their supporting South on the Korean Peninsula, then Seoul would face a dilemma.South Is Caught between the United States and ChinaCompared with the potential impact of the South Sea disputes on South Korea's relations with the United States and China, the dilemma with the ASEAN countries is secondary. …
