U.S. ratification of UNCLOS won't help resolve disputes in South China Seas
Ratification of UNCLOS will neither sway China nor guarantee U.S. navigational rights in the South China Seas any more than continued U.S. naval presence through the Freedom of Navigation program.
Quicktabs: Arguments
Ratification of UNCLOS will neither sway China nor guarantee U.S. navigational rights in the SCS which are advanced not by membership in a treaty, but by maintaining a strong Navy, conducting persistent naval operations against China’s excessive maritime claims, supporting key U.S. allies, and adhering to long-standing principles of the customary international law of the sea.
The customary international law of the sea— which includes the principles of freedom of the seas, “innocent passage” through territorial waters, and passage rights through international straits and archipelagoes—existed long before UNCLOS was adopted in 1982. The convention merely codified and elaborated upon these widely accepted principles. While not a party to UNCLOS, the United States— unlike China—actually honors the convention’s provisions. The United States demarcates legitimate maritime boundaries, respects the rights of coastal states within their EEZs and territorial seas, and adheres domestically to the regimes regarding the contiguous zone and EEZ.
No evidence suggests that China, or any other state, would respect its obligations under UNCLOS to a greater extent if the United States became a party. Nor is there any evidence that ratification of UNCLOS would enhance U.S. military capability. The Freedom of Navigation program, the primary means of the U.S. confronting China’s exces- sive claims, does not rely on U.S. membership in UNCLOS.
Regardless, the United States cannot afford to wait to join UNCLOS before bringing a decisive res- olution to the challenges in the SCS. The Senate Foreign relations Committee has taken the convention under consideration on many occasions, including hearings in 1994, 2003, 2004, and 2007. The committee held four hearings in 2012, but then-chairman Senator John Kerry (D–MA) did not attempt to offer the convention for a committee vote due to stiff opposition by the convention’s detractors.
There is no realistic possibility that the United States will ratify UNCLOS in the near term, or perhaps ever. U.S. policymakers should instead concentrate their efforts on developing and implementing a specific strategy to address intractable problems, such as those the United States faces in the SCS.
Opponents of the United States becoming a party to UNCLOS argue or might argue one or more of the following:
- China’s ability to cite international law (including UNCLOS) in defending its position on whether coastal states have a right to regulate foreign military activities in their EEZs73 shows that UNCLOS does not adequately protect U.S. interests relating to navigational rights in EEZs; the United States should not help lock this inadequate description of navigational rights into permanent international law by becoming a party to the treaty.
- The United States becoming a party to the treaty would do little to help resolve maritime territorial disputes in the SCS and ECS, in part because China’s maritime territorial claims, such as those depicted in the map of the nine-dash line, predate and go well beyond what is allowed under the treaty and appear rooted in arguments that are outside the treaty.
- The United States can adequately support the ASEAN countries and Japan in matters relating to maritime territorial disputes in the SCS and ECS in other ways, without becoming a party to the treaty.
- The United States can continue to defend its positions on navigational rights on the high seas by citing customary international law, by demonstrating those rights with U.S. naval deployments (including those conducted under the FON program), and by having allies and partners defend the U.S. position on the EEZ issue at meetings of UNCLOS parties.
I understand the force of this argument. The U.S. already adheres the key principles in UNCLOS, so joining UNCLOS will allow the U.S. to push back more effectively against China’s aggressive and expansionary activities.
But is there really any evidence that formal accession would change China’s view of the U.S. position on UNCLOS issues? China is already a member of UNCLOS and other countries (like Japan and the Philippines) are also members of UNCLOS. But I don’t think UNCLOS has really bolstered their effectiveness in pushing back against China. Moreover, as Professor Dutton explains, China has a radically different interpretation of its authority to regulate foreign ships and aircraft in its Exclusive Economic Zone under UNCLOS. How will joining UNCLOS help the U.S. change China’s interpretation of UNCLOS?
As a practical matter, UNCLOS does have a way of compelling member states to conform their interpretations: mandatory dispute settlement in the International Tribunal for the Law of the Sea or in Annex VII arbitration. But as China and Russia have demonstrated in recent years, these mechanisms are not likely to be a serious constraint, especially on questions that touch sovereignty (which is how China frames most of its activities). I suppose if the U.S. joins UNCLOS, and subjects itself to UNCLOS dispute settlement, that might make a difference. But I don’t think it would be a very large one (after all, Japan, China, and the Philippines are all already subject to UNCLOS dispute settlement, which has accomplished little so far).
