Abstract Important events relating to the sovereignty dispute over the Spratly Islands have arisen by fits and starts since 2009, marking the start of a new phase in the legal battle over territorial and maritime claims in the South China Sea. While the exchange of legal arguments between the parties has gradually laid bare their maritime claims, much still remains shrouded in uncertainty. Among the obscure claims wanting clarification is China's infamous nine-dotted-line map, which in 2011 elicited a response and counterresponse between the Philippines and China. This article examines the maritime and territorial claims of the Philippines and China as revealed in the recent discord over the nine-dotted-line map. Keywords: Chinathe PhilippinesSouth China Sea Acknowledgments This article benefits extensively from an online discussion organized by the Centre for South China Sea Studies, Diplomatic Academy of Vietnam. Special thanks go to Duong Danh Huy, Nguyen Thi Thanh Ha, Tran Truong Thuy, Tran Van Thuy, and Vu Hai Dang, whose comments and interventions made the authors alter some of their original views. Nguyen-Dang Thang would also like to thank Barbara Miltner and Zhen Sun for valuable materials and linguistic counsel. The usual disclaimer applies. Notes 1. Since the People's Republic of China (China) and the Republic of China (Taiwan) maintain broadly similar claims on the South China Sea (SCS) issues, the discussion in this article focuses on the positions of the former and highlight, where necessary, the views of the latter. For comparison of the claims, see Yann-Huei Song and Zou Keyuan, “Maritime Legislation of Mainland China and Taiwan: Developments, Comparison, Implications, and Potential Challenges for the United States,” Ocean Development and International Law 31 (2000): 303–345. For a recent study on the Taiwanese claim, see Kuan-Hsiung Wang, “The ROC's Maritime Claims and Practices with Special Reference to the South China Sea,” Ocean Development and International Law 41 (2010): 237–252. 2. See Clive Schofield, “Dangerous Ground: A Geopolitical Overview of the South China Sea,” in Security and International Politics in the South China Sea: Towards a Co-operative Management Regime, eds. S. Bateman and R. Emmers (London: Routledge, 2009), 7–25, 12–18. He comments that the features of the Spratly Islands do not have much intrinsic value in themselves with the issue being the potential to generate large maritime zones and hence entitle claimant states to exploit marine natural resources there, particularly oil and gas. 3. The Commission on the Limits of the Continental Shelf (CLCS) was established pursuant to the United Nations Convention on the Law of the Sea, Montego Bay, 10 December 1982, 1833 U.N.T.S. 396 (LOS Convention), see the CLCS Web site at www.un.org/Depts/los/clcs_new/clcs_home.htm.Annex II, Article 4, provides that a coastal state is to make its submission with respect to the outer limit of its continental shelf beyond 200 nautical miles to the CLCS no later than 10 years after the entry into force of the Convention in relation to that state. Given the difficulty that developing countries face in meeting this original timeline, the states parties to the LOS Convention set 13 May 1999, the date of the CLCS's adoption of the Scientific and Technical Guidelines, as the starting date for the calculation of the 10-year time limit. See “Decision regarding the date of commencement of the ten-year period for making submissions to the Commission on the Limits of the Continental Shelf set out in article 4 of Annex II to the United Nations Convention on the Law of the Sea,” SPLOS/72, 29 May 2001, paragraph a, available at the Web site of the UN Division for Ocean Affairs and the Law of the Sea (DOALOS), www.un.org/Depts/los/index.htm. For background on the issue, see “Issues with respect to article 4 of Annex II to the Convention (ten-year time limit for submissions),” at the DOALOS Web site. 4.

Malaysia, though stating that its submission to the Commission constituted a legitimate undertaking under the LOS Convention, refrained from addressing directly China's nine-dotted-line claim and stated only that the submission was without prejudice to, inter alia, “the position [sic] of States which are parties to a land or maritime dispute in consonance with Paragraph (5) of Annex I to the [CLCS's] Rules of Procedure.” Malaysia, Note Verbale No. HA 24/09, 20 May 2009, available at the CLCS Web site, supra note 3.For Vietnam's reaction, see Note Verbale No. 86/HC-2009, 8 May 2009, available at the CLCS Web site, supra note 3. 10.

See also “Remarks by Secretary Hilary Clinton at the 17th ARF Meeting in Hanoi on 23 July 2010,” where she stated that “consistent with customary international law, legitimate claims to maritime space in the South China Sea should be derived solely from legitimate claims to land features,” available at www.state.gov/secretary/rm/2010/07/145095.htm (accessed 27 May 2011). 11. No official position has been revealed as to the meaning and legal basis of the lines. Reportedly Taiwan is of the view that the nine dotted lines delineate historic waters. See Nien-Tsu Alfred Hu, “South China Sea: Troubled Waters or a Sea of Opportunity?” Ocean Development and International Law 41 (2010): 203–213, 207. Chinese scholars have been active in their discussion of the lines, but their arguments are deeply divided on both the validity and meaning of the lines. Even among those who think that the lines are defensible under international law, opinions differ and change over time. See, for example, Gao Zhiguo, “The South China Sea: From Conflict to Cooperation,” Ocean Development and International Law 25 (1994): 345–359, and Kuan-Hsiung Wang, supra note 1 (for the view that the dotted lines serve to allocate island sovereignty rather than to delimit maritime boundary); Zou Keyuan, “The Chinese Traditional Maritime Boundary Line in the South China Sea and Its Legal Consequences for the Resolution of the Dispute over the Spratly Islands,” International Journal of Marine and Coastal Law 14 (1999): 27–55 (for the view that the nine dotted lines define islands under China's sovereignty and their adjacent waters that are not yet defined); Zou Keyuan, “Historic Rights in International Law and in China's Practice,” Ocean Development and International Law 32 (2001): 149–168 (for the view that the maps depict the scope of Chinese historic rights, which do not amount to full sovereignty but only “tempered sovereignty” in the SCS); Ji Guoxing, “Outer Continental Shelf Claims in the South China Sea: A New Challenge to China's U-Shaped Line,” in International Workshop on Non-traditional Security Cooperation in the South China Sea (Haikou, 2010) (supporting the “tempered sovereignty” view); Peter Kien-Hong Yu, “The Chinese (Broken) U-shaped Line in the South China Sea: Points, Lines, and Zones,” Contemporary Southeast Asia: A Journal of International and Strategic Affairs 25 (2003): 405–430 (for the view that the line delimit China's historic waters); and Li Jinming and Li Dexia, supra note 7 (for the view that the lines are a traditional maritime boundary with dual functions to define China's sovereignty over the Paracel and Spratly Islands and to delimit according to the median line principle the maritime zones of China and the coastal states concerned). See also Zou Keyuan, “The Chinese Traditional Maritime Boundary Line in the South China Sea and Its Legal Consequences for the Resolution of the Dispute over the Spratly Islands,” International Journal of Marine and Coastal Law 14 (1999): 27–55, and Zou Keyuan, “South China Sea Studies in China: Achievements, Constraints and Prospects,” Singapore Year Book of International Law 11 (2007): 88–92 (for a useful summary of conflicting views in the Chinese literature on this issue). 12. See Vietnam's 2009 Note Verbale, supra note 9. Vietnam, like Malaysia, also states that its submissions constituted legitimate undertakings in implementation of the obligations of the states parties to the LOS Convention. 13. Besides the Spratly Islands dispute, there is a bilateral sovereignty dispute over the Paracel Islands that lie to the north of the SCS. For an account of island disputes in bilateral relations between China and Vietnam, see Monique Chemillier-Gendreau, Sovereignty over the Paracel and Spratly Islands (The Hague: Kluwer Law International, 2000). 14.

In acknowledging that “there is no clear explanation as to the legal basis, the method of drawing, and the status of those separated dotted-lines,” Indonesia formulated its proposition in a tentative manner, using “it seems that” as the introductory phrase. Such prudence is necessary because Indonesia, a third party in the SCS island disputes, could not challenge the nine dotted lines were they only to denote China's sovereignty over islands, a view long held by Indonesia. See H. Djalal, “South China Sea Island Disputes,” Raffles Bulletin of Zoology Supplement 8 (2000): 9–21. 16. Indonesia's 2010 Note Verbale, supra note 10, para. 4. 17. Ibid., para. 3. 18.

Samuels, Contest for the South China Sea (New York: Methuen, 1982). 21. A useful summary and review of claims to the Spratly Islands is in Daniel J. Dzurek, “The Spratlys Island Dispute: Who's on First?” Maritime Briefings 2 (1996): 1; Mark J. Valencia, Jon M. Van Dyke, and Noel A. Ludwig, Sharing the Resources of the South China Sea (The Hague: Martinus Nijhoff, 1997), chap. 3; Ralf Emmers, Geopolitics and Maritime Territorial Disputes in East Asia (London: Routledge, 2009), chap. 4; and McDorman, supra note 5, at 512–521. 22. Other islands claimed by China include the Paracel Islands (also claimed by Taiwan and Vietnam), the Pratas Islands (controlled by Taiwan), and Scaborough Reef (also claimed by the Philippines). See Jeanette Greenfield, China's Practice in the Law of the Sea (Oxford: Clarendon Press, 1992), 149–59. Regarding the Scarborough Reef, see infra note 55 and accompanying text. 23. The official position is stated in China, “Historical Evidence to Support China's Sovereignty over Nansha Islands,” 17 November 2000, available at www.fmprc.gov.cn/eng/topics/3754/t19231.htm (accessed 14 February 2009). 24. See ibid.; and Li Jinming and Li Dexia, supra note 7, at 289. 25. For an account of the history of the nine dotted lines, see Zou Keyuan, “The Chinese Traditional Maritime Boundary,” supra note 11, 32–34; and Li Jinming and Li Dexia, supra note 7. The early maps depicted eleven lines, but the two lines in the Gulf of Tonkin have been removed since 1953. 26. The distance between Hainan Island, China's southernmost mainland area, and the nearest feature of the Spratly Islands is more than 500 nautical miles. 27. LOS Convention, supra note 3, Article 121 makes a distinction between an island and a rock. The former is entitled to an EEZ and continental shelf while the latter is not. 28. China, Exclusive Economic Zone and Continental Shelf Act of 26 June 1998, available at the DOALOS Web site, supra note 3. 29. China, Law on the Territorial Sea and the Contiguous Zone of 25 February 1992, available at the DOALOS Web site, supra note 3. 30. EEZ and Continental Shelf Act, supra note 28. 31. The dominant view among Chinese scholars is that the geographic scope of China's historic rights in the SCS is defined by the nine dotted lines. Many scholars also argue that the lines are the median line between China's islands on the one hand and the relevant coasts of the other states on the other. See Li Jinming and Li Dexia, supra note 7, at 294; and Kuan-Hsiung Wang, supra note 1. But see infra note 107 and accompanying text. 32. Zou Keyuan, “Historic Rights,” supra note 11, suggests that the contents of the historic rights are first “sovereign rights to the water column.” But he does not explain how these rights have crystallized. It is improbable that such historic fishing rights were claimed in 1947 when China adhered to the view that the territorial sea could not extend beyond 3 nautical miles, leaving much of the SCS open to fishing. On the other hand, it is unreasonable to think that China reduced its sovereignty-like historic rights to something less than sovereignty. 33. China's 2009 Notes Verbale, supra note 8. 34. McDorman, supra note 5, at 514. This interpretation appears to treat the phrase “see attached map” bracketed at the end of the sentence to complement the immediate preceding phrase where China claims that it “enjoys sovereign rights and jurisdiction over the relevant waters as well as the seabed and subsoil thereof.” China's 2009 Notes Verbale, supra note 8. An alternative interpretation is that the map depicts the scope of China's claims stated in the entire sentence; that is, to include “sovereignty over the islands in the SCS and the adjacent waters.” 35. This was expressed in China's reaction to Japan's 2008 submission to the CLCS. Japan, “Executive Summary: Submission to the Commission,” 12 November 2008, available at the CLCS Web site, supra note 3. China, Note Verbale No. CML/2/2009, 6 February 2009, available at the CLCS Web site, supra note 3. See also McDorman, supra note 5, at 514–515, for a discussion. Indonesia's 2010 Note Verbale, supra note 10, also mentioned two statements by Chinese representatives at Law of the Sea Conferences where the same position was stated. 36. McDorman, supra note 5, at 514. 37. Ibid., at 515. 38. The most significant feature not claimed by the Philippines is the Spratly Island. See Valencia, Van Dyke, and Ludwig, supra note 21, at 33. 39. This name was considered a tactic by the Philippines to distinguish its claim from other claims to the Spratly Islands. This distinction is no longer maintained by the Philippines. See Dzurek, supra note 21, at 21. The name Kalayaan, which means Freedomland, is however believed to have been coined by Thomas Cloma. See infra note 40. 40.
