🗺️ Introduction: What Is the South China Sea Dispute?
The South China Sea is one of the world's most contested maritime regions. Countries including China, Vietnam, the Philippines, Malaysia, Brunei, and Taiwan have overlapping claims over the archipelago and surrounding waters, primarily due to economic resources, military positioning, and strategic shipping lanes.
With tensions often escalating, the region represents a flashpoint for potential military conflict, making it a central topic in discussions of East Asian security and international maritime law.
🇨🇳 China’s Expanding Maritime Claims
Since the 1980s, China has shifted its focus to modernizing its navy and asserting broader maritime sovereignty. In February 1992, the National People's Congress passed a Law of the Sea, claiming four key island groups and declaring adjacent waters as “internal waters.” This declaration gave China authority over vessels passing through, and even suggested rights to repel foreign ships and aircraft.
Such unilateral actions marked a sharp contrast to China’s stated commitment to peaceful dispute resolution and have since raised doubts about its diplomatic sincerity.
⚔️ Rising Diplomatic Tensions: Mischief Reef and Beyond
A pivotal moment occurred in 1995 when the Philippines discovered Chinese telecommunications equipment on Mischief Reef, leading to protests and heightened tensions. This marked the first serious territorial clash between China and a claimant other than Vietnam.
As China continues to build infrastructure on disputed reefs, including military airstrips and naval bases, regional powers like Vietnam, the United States, and Japan have become increasingly concerned.
📜 China’s Historical Justifications
China supports its claims with historical documents dating back to the 2nd century BC, Tang and Song dynasty naval records, ancient ceramics, and maritime maps from the Yuan and Ming dynasties. However, critics argue that historical visits or map markings do not constitute legal sovereignty, especially for islands 1,000 km from the mainland.
⚖️ Legal Disputes and the Role of International Law
Under the United Nations Convention on the Law of the Sea (UNCLOS), many of the features China claims are not eligible for exclusive economic zones (EEZs) or continental shelves. Despite a 2016 ruling in favor of the Philippines, China has continued to reject international arbitration outcomes.
This legal tension underscores the challenges of enforcing international maritime law against major powers.
🔥 Economic and Strategic Stakes in the South China Sea
Beyond territorial claims, the South China Sea holds immense strategic value. It connects Southeast Asia to major markets like South Korea, Japan, and the U.S. West Coast, and is rich in oil, gas, and fishery resources.
China's construction of a 2,600-meter airstrip, and submarine and destroyer ports in the West Philippine Sea, shows its commitment to securing dominance over this key maritime region.
🌏 ASEAN & Global Reactions
In response to China’s assertiveness, ASEAN nations have pushed for peaceful dispute resolution. In 1995, ASEAN foreign ministers released a statement emphasizing peace. The ASEAN Regional Forum (ARF) further encouraged respect for international law in 1996.
Despite these efforts, tensions persist, and countries like Japan remain vigilant, fearing disruption to maritime energy supply chains.
🧭 Implications for Korea and Regional Security
For South Korea, the South China Sea issue has significant implications—not just for trade, but also as a parallel to its own Dokdo territorial dispute. With the region seen as a "resource treasure trove" and vital trade route, South Korea has growing reasons to engage in regional security cooperation.
✅ Conclusion: A Tense and Unresolved Maritime Conflict
The South China Sea dispute remains unresolved, characterized by rising geopolitical competition, overlapping sovereignty claims, and growing military presence. With China pushing hard for dominance and neighboring countries seeking legal and diplomatic countermeasures, the region’s stability hinges on multilateral dialogue and international law.
