Tides of Chance: Exploring the Consequences of China’s UNCLOS Ratification for U.S. Maritime Interests

By: Ammar Asad

Introduction

Amid the ever-changing landscape of international diplomacy, China’s engagement with the United Nations Convention on the Law of the Sea (UNCLOS) is a major transformation. This key development could chart a new course for international maritime policy and influence, with considerable implications for U.S. maritime interests across the expansive and dynamic oceanic realms.

This article offers a clear, informative look at how this move could reshape the maritime landscape for the United States. From the strategic chessboard of naval power to the legal frameworks that govern the world’s oceans, this post sails through the potential impacts and opportunities that lie ahead. So, hoist the sails and prepare to cross through the currents of this transformative development in global maritime affairs.

Setting the Stage

The United Nations Convention on the Law of the Sea (UNCLOS), an international agreement, was established in 1982 and became effective in 1994 after years of negotiation, aiming to regulate ocean governance, including territorial waters, navigation rights, and resource exploitation.

In the context of maritime law and national priorities, the U.S. has chosen not to join the UNCLOS, maintaining a stance from the Reagan administration that values national sovereignty and the autonomy of its military activities.

Additionally, the U.S. maintains the ability to engage in deep seabed mining activities without UNCLOS ratification, under the conditions set by its own legislation. On the other side of the Pacific, China’s approval of UNCLOS in 1996 underscores its strategic approach to maritime claims, particularly in the contentious South China Sea region, where it faces disputes with neighboring states over territorial sovereignty. This alignment with UNCLOS by China is a calculated move within the complex chessboard of international maritime policy, where legal frameworks intersect with geopolitical ambitions.

China’s Strategic Ratification and Its Implications

China’s ratification of UNCLOS in 1996 was a strategic move designed to grow its expansive claims in the South China Sea. By joining the treaty, China gained a veneer of international legitimacy, selectively leveraging provisions related to Exclusive Economic Zones and the rights of archipelagic states. This tactic allows China to assert sovereignty over contested islands and reefs, fueling its land reclamation projects, artificial island construction, and increased military presence. The implications are far-reaching:

  • “Nine-Dash Line” Encroachment: China’s “nine-dash line” severely encroaches on neighboring countries’ territorial waters, escalating tensions and destabilizing the region.
  • Navigational Rights Clash: China’s interpretation of navigational rights under UNCLOS clashes with the United States and other nations that uphold freedom of navigation in international waters.
  • Regional Power Shift: The South China Sea has become a major flashpoint, highlighting China’s ambition to reshape the maritime order and challenge the existing rules-based system, despite the 2016 international arbitration ruling that undermined the legal basis for many of its claims.

What It Means for the U.S.

China’s strategic approach to the United Nations Convention on the Law of the Sea (UNCLOS) and its assertive stance in the South China Sea have significant implications for the United States, which remains outside the treaty. Here’s an overview:

  • Principles in Conflict: China’s expansive “nine-dash line” claims, which challenge the UNCLOS framework, directly confront the U.S. principle of freedom of navigation—a principle upheld by ongoing U.S. Freedom of Navigation Operations.

  • Uncertain Footing: While the U.S. defends its maritime stance based on customary international law, its non-participation in UNCLOS weakens these claims, allowing China to depict the U.S. as an external disruptor.

  • Forfeiting Influence: Not joining UNCLOS means the U.S. forfeits a chance to help shape maritime law, potentially leading to future regulations that may not align with U.S. interests.

  • The Ratification Debate: The question of whether the U.S. should ratify UNCLOS is complex. Proponents argue it would bolster the U.S. position in maritime disputes, while opponents express concerns over ceding authority to international bodies and restricting national autonomy. China’s increasing assertiveness adds urgency to this ongoing discussion.

The Ripple Effects

China’s embrace of UNCLOS and its actions in the South China Sea go way beyond just a U.S.-China standoff. Here’s why this matters to the whole world:

  • The Trade Lifeline: The South China Sea is like a giant artery for global trade. If things get messy there, everyone with an interest in stable trade routes feels the pain. China’s aggressive stance is making a lot of countries nervous.
  • Strained Relationships: China’s actions clash with the claims of its neighbors, many of whom are close U.S. allies or partners. This risks destabilizing the whole Asia-Pacific region and puts a strain on existing security agreements.
  • Challenging the Rules: China is picking and choosing the parts of UNCLOS it likes, flouting the rest. This undermines the whole idea of a rules-based system for handling oceans and the resources in them. We could end up in a world where ‘might makes right’ on the high seas, hurting efforts to manage things peacefully and sustainably.
  • America the Outsider: The irony is that the U.S., one of the world’s biggest naval powers, isn’t a part of UNCLOS. This makes it harder to uphold the current system and leaves room for others to rewrite the rules. Maybe it’s time for the U.S. to join the club, so its voice is fully heard on these critical issues.

Other Countries’ Ratification and Comparison

The ratification of the United Nations Convention on the Law of the Sea (UNCLOS) reflects the diverse priorities and strategic considerations of nations around the globe. Coastal and island nations in the Pacific and Southeast Asia, such as the Philippines, Vietnam, and Malaysia, have widely ratified UNCLOS, valuing its framework for maintaining territorial integrity, maritime rights, and peaceful dispute resolution. These countries often see the convention as a vital safeguard against the assertive maritime claims of more powerful neighbors, notably China.

In contrast, the United States avoidance of UNCLOS, citing concerns over sovereignty, jurisdictional overreach, and the potential impact on military operations. This has resulted in the paradoxical situation where the world’s largest naval power is not formally bound by the primary international treaty that governs the oceans, which could be seen as a challenge to the global maritime order.

The dichotomy between states that have ratified UNCLOS and those that have not underscores the complexities of international maritime law and the varying priorities across nations. 

Ratifying states typically advocate for a rules-based international order and the peaceful settlement of conflicts, while non-ratifying states, such as the U.S., may give precedence to national sovereignty and operational flexibility.

In the context of UNCLOS, China leverages its ratification status to bolster its maritime claims, particularly in the South China Sea, while the U.S. continues to rely on established customary international law and its formidable naval capabilities to maintain its maritime interests.

Environmental Implications: Beyond Geopolitics

The tussle between China and the United States over UNCLOS and maritime dominance extends beyond geopolitical maneuvering; it harbors significant environmental implications. The ocean, a shared global resource, is at the mercy of the decisions made by these two maritime giants.

  1. Safeguarding Marine Ecosystems: The South China Sea, a hotspot of marine biodiversity, faces threats from overfishing, pollution, and habitat destruction due to increased militarization and land reclamation. The aggressive posturing and development activities compromise the ecological balance, endangering species and disrupting fisheries that millions depend on for their livelihood.
  2. Climate Change and Rising Seas: As signatories to UNCLOS, nations are obligated to protect and preserve the marine environment. However, China’s selective adherence to the treaty’s provisions raises concerns about its commitment to environmental stewardship. The United States, despite its non-ratification, has a crucial role in advocating for sustainable ocean practices and addressing climate change impacts, such as rising sea levels and ocean acidification.
  3. Collaborative Conservation Efforts: The complex challenges facing the world’s oceans, from climate change to plastic pollution, necessitate a collaborative approach. By engaging constructively in UNCLOS and other international frameworks, China and the United States can lead global efforts to protect marine ecosystems, promote sustainable use of ocean resources, and foster resilience against environmental threats.

In conclusion, the environmental stakes in the ongoing UNCLOS discourse are high. The actions of China and the United States not only shape the future of maritime law and geopolitics but also the health of our planet’s oceans.

Both nations bear a responsibility to prioritize sustainable practices and cooperation over unilateral ambitions, ensuring that the oceans remain a source of life and prosperity for generations to come.Top of Form

Unsettled Waters: The Future of Ocean Governance

China’s ratification of the UNCLOS has dramatically altered the maritime landscape. Its selective application of the treaty to aggressively expand territorial claims in the South China Sea directly confronts U.S. interests and undermines the treaty’s intended purpose of resolving disputes peacefully. The U.S.’s continued non-ratification of UNCLOS leaves it in a precarious position, hindering its ability to fully shape international maritime law and potentially eroding its influence in upholding the rules-based order.

The geopolitical consequences of this dynamic are far-reaching. China’s actions escalate tensions in the Asia-Pacific region, strain partnerships with U.S. allies, and threaten the stability of vital global trade routes. The stark contrast between China’s ratification and the U.S.’s abstention reveals the vulnerabilities inherent in the current system of ocean governance.

The time for passive observation is over. The United States must urgently decide its stance on UNCLOS and the future of maritime law. Continued indecision risks ceding ground to a vision of ocean governance where unilateral interpretations and unchecked expansionism prevail. The world’s oceans demand a comprehensive and universally accepted legal framework to ensure their sustainable use and prevent further escalation of conflict.
