The South China Sea (SCS) has emerged as one of the world’s most contested maritime regions, encapsulating a range of complex issues from territorial disputes to freedom of navigation. The importance of the South China Sea extends beyond regional boundaries due to its strategic geopolitical position and its critical role in international trade. By employing Kenneth Waltz’s neorealism and a geopolitical framework, we can gain deeper insights into the ongoing tensions and power dynamics that characterize this vital region.

The Strategic Importance of the South China Sea

The South China Sea is a semi-enclosed sea, covering approximately 3.5 million square kilometers and surrounded by several Southeast Asian nations, including China, Vietnam, the Philippines, Malaysia, Brunei, and Taiwan. It is not only rich in natural resources such as oil and natural gas but also a crucial maritime corridor through which over a third of global shipping passes, amounting to trillions of dollars in trade annually. This makes the SCS a focal point for regional and global powers alike.

Neorealism: Understanding State Behavior

Kenneth Waltz’s neorealism, or structural realism, provides a framework for analyzing international relations by emphasizing the anarchic nature of the international system. According to Waltz, states are the primary actors in the international arena and operate within a system lacking a central authority. This leads to a self-help system where states prioritize their survival, security, and relative power.

Security Dilemma in the South China Sea

In the context of the South China Sea, the security dilemma—a core concept in neorealism—explains much of the behavior of the involved states. The presence of overlapping territorial claims, particularly China’s expansive “Nine-Dash Line” claim, exacerbates tensions and mistrust among regional states. China’s construction of artificial islands and militarization in the region can be viewed as measures to increase its security and extend its influence. However, these actions provoke insecurity among other claimants and external powers like the United States, which has strategic interests in maintaining freedom of navigation.

Balance of Power

Neorealism posits that states strive to balance power to prevent any one state from achieving hegemonic dominance. In the South China Sea, regional states such as Vietnam and the Philippines have sought to balance China’s growing power by strengthening their military capabilities and seeking alliances with external powers. The United States, as a global power, plays a pivotal role in this balancing act by conducting “freedom of navigation” operations and strengthening security partnerships with Southeast Asian nations to counter China’s assertive behavior.

Geopolitical Framework: Strategic and Economic Dimensions

While neorealism focuses on the structural aspects of international relations, a geopolitical framework provides an understanding of the strategic and economic factors driving state behavior in the South China Sea.

Geostrategic Significance

Geopolitically, the South China Sea serves as a critical juncture between the Pacific and Indian Oceans, making it a strategic chokepoint for maritime trade routes. Control over this region offers significant strategic advantages, including the ability to influence sea lines of communication and project power. China’s actions in the South China Sea can be seen as an attempt to assert control over this geostrategic space and secure its maritime periphery against potential encirclement by rival powers.

Economic Imperatives

The economic potential of the South China Sea, with its abundant fisheries and potential oil and gas reserves, further fuels the competition. For China, securing access to these resources is crucial for sustaining its economic growth and energy security. Similarly, other claimant states view these resources as vital for their economic development and national interests.

Regional Power Dynamics

The South China Sea disputes are also a reflection of broader regional power dynamics. China’s rise as a regional and global power challenges the existing order, leading to tensions with neighboring countries and the United States. The Association of Southeast Asian Nations (ASEAN) plays a significant role in attempting to mediate disputes and foster dialogue, though its effectiveness is often hampered by the divergent interests of its member states.

The Role of International Law

While neorealism emphasizes power dynamics, international law also plays a crucial role in the South China Sea disputes. The United Nations Convention on the Law of the Sea (UNCLOS) provides a legal framework for resolving maritime disputes. In 2016, the Permanent Court of Arbitration in The Hague ruled against China’s claims in favor of the Philippines. However, China’s rejection of the ruling underscores the limitations of international law in resolving power-driven conflicts.

Prospects for the Future

The future of the South China Sea remains uncertain, with potential scenarios ranging from peaceful resolution through diplomacy to increased militarization and conflict. The continued involvement of external powers, particularly the United States, will significantly influence the regional balance of power.

Cooperative Security Approaches

One potential pathway towards stability in the South China Sea is the adoption of cooperative security approaches that emphasize dialogue, confidence-building measures, and joint resource management. Multilateral frameworks involving ASEAN and other stakeholders could facilitate negotiations and reduce tensions.

The Role of Great Powers

The behavior of great powers, particularly China and the United States, will be pivotal in shaping the future trajectory of the South China Sea. Acknowledging each other’s core interests and establishing mechanisms to prevent accidental escalation could help manage tensions and maintain regional stability.

Conclusion

The South China Sea epitomizes the complexities of contemporary international relations, where power politics, strategic interests, and legal frameworks intersect. By applying Kenneth Waltz’s neorealism and a geopolitical framework, we can better understand the underlying dynamics driving state behavior in this critical region. As global power shifts continue to unfold, the South China Sea will remain a crucial arena for understanding the interplay between national interests and the broader international system.
