China's Actions in South and East China Seas: …

1 Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China : Issues for Congress Ronald O'Rourke Specialist in Naval Affairs December 12, 2017 Congressional Research Service 7-5700 R42784 Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China Congressional Research Service Summary China s Actions for asserting and defending its maritime territorial and exclusive economic zone (EEZ) claims in the East China (ECS) and South China Sea (SCS) have heightened concerns among observers that China may be seeking to dominate or gain control of its near-seas region, meaning the ECS, the SCS, and the Yellow Sea.

2 Chinese domination over or control of this region could substantially affect strategic, political, and economic interests in the Asia-Pacific region and elsewhere. China is a party to multiple territorial disputes in the SCS and ECS, including, in particular, disputes over the Paracel Islands, Spratly Islands, and Scarborough Shoal in the SCS, and the Senkaku Islands in the ECS. China depicts its territorial claims in the SCS using the so-called map of the nine-dash line that appears to enclose an area covering roughly 90% of the SCS.

3 Some observers characterize China s approach for asserting and defending its territorial claims in the ECS and SCS as a salami-slicing strategy that employs a series of incremental Actions , none of which by itself is a casus belli, to gradually change the status quo in China s favor. In addition to territorial disputes in the SCS and ECS, China is involved in a dispute, particularly with the United States, over whether China has a right under international law to regulate the activities of foreign military forces operating within China s EEZ.

4 The dispute appears to be at the heart of incidents between Chinese and ships and aircraft in international waters and airspace in 2001, 2002, 2009, 2013, and 2014. The position on territorial and EEZ disputes in the Western Pacific (including those involving China ) includes the following elements, among others: The United States supports the principle that disputes between countries should be resolved peacefully, without coercion, intimidation, threats, or the use of force, and in a manner consistent with international law.

5 The United States supports the principle of freedom of seas, meaning the rights, freedoms, and uses of the sea and airspace guaranteed to all nations in international law. The United States opposes claims that impinge on the rights, freedoms, and lawful uses of the sea that belong to all nations. The United States takes no position on competing claims to sovereignty over disputed land features in the ECS and SCS. Although the United States takes no position on competing claims to sovereignty over disputed land features in the ECS and SCS, the United States does have a position on how competing claims should be resolved: Territorial disputes should be resolved peacefully, without coercion, intimidation, threats, or the use of force, and in a manner consistent with international law.

6 Claims of territorial waters and EEZs should be consistent with customary international law of the sea and must therefore, among other things, derive from land features. Claims in the SCS that are not derived from land features are fundamentally flawed. Parties should avoid taking provocative or unilateral Actions that disrupt the status quo or jeopardize peace and security. The United States does not believe that large-scale land reclamation with the intent to militarize outposts on disputed land features is consistent with the region s desire for peace and stability.

7 Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China Congressional Research Service The United States, like most other countries, believes that coastal states under UNCLOS have the right to regulate economic activities in their EEZs, but do not have the right to regulate foreign military activities in their EEZs. military surveillance flights in international airspace above another country s EEZ are lawful under international law, and the United States plans to continue conducting these flights as it has in the past.

8 The Senkaku Islands are under the administration of Japan and unilateral attempts to change the status quo raise tensions and do nothing under international law to strengthen territorial claims. China s Actions for asserting and defending its maritime territorial and EEZ claims in the ECS and SCS raise several potential policy and oversight issues for Congress, including whether the United States has an adequate strategy for countering China s salami-slicing strategy, whether the United States has taken adequate Actions to reduce the risk that the United States might be drawn into a crisis or conflict over a territorial dispute involving China .
