37. Between 30 August and 3 September 2011, President Benigno S. Aquino III of the Philippines paid a State visit to China. On 1 September 2011, the two sides issued a Joint Statement between the People' s Republic of China and the Republic of the Philippines, which, in paragraph 15, "reiterated their commitment to addressing the disputes through peaceful dialogue" and "reaffirmed their commitments to respect and abide by the Declaration on the Conduct of Parties in the South China Sea signed by China and the ASEAN member countries in 2002" . The Joint Statement, consequently, reaffirmed Paragraph 4 of the DOC relating to settlement of relevant disputes by negotiations.

38. The bilateral instruments between China and the Philippines repeatedly employ the term "agree" when referring to settlement of their disputes through negotiations. This evinces a clear intention to establish an obligation between the two countries in this regard. Paragraph 4 of the DOC employs the term "undertake" , which is also frequently used in international agreements to commit the parties to their obligations. As the ICJ observed in its Judgment in Bosnia and Herzegovina v. Serbia and Montenegro, "[t]he ordinary meaning of the word 'undertake' is to give a formal promise, to bind or engage oneself, to give a pledge or promise, to agree, to accept an obligation. It is a word regularly used in treaties setting out the obligations of the Contracting Parties .... It is not merely hortatory or purposive" (Application of the Convention on the Prevention and Punishment of the Crime of Genocide (Bosnia and Herzegovina v. Serbia and Montenegro), Judgment of 26 February 2007, I.C.J. Reports 2007, p. 111, para. 162). Furthermore, under international law, regardless of the designation or form the above-mentioned instruments employ, as long as they intend to create rights and obligations for the parties, these rights and obligations are binding between the parties (Cf. Maritime Delimitation and Territorial Questions between Qatar and Bahrain (Qatar v. Bahrain), Jurisdiction and Admissibility, Judgment of 1 July 1994, I.C.J. Reports 1994, pp. 120-121, paras. 22-26; Land and Maritime Boundary between Cameroon and Nigeria (Cameroon v. Nigeria: Equitorial Guinea intervening), Judgment of 10 October 2002, I.C.J. Reports 2002, pp. 427, 429, paras. 258, 262-263).

39. The relevant provisions in the aforementioned bilateral instruments and the DOC are mutually reinforcing and form an agreement between China and the Philippines. On that basis, they have undertaken a mutual obligation to settle their relevant disputes through negotiations.

40. By repeatedly reaffirming negotiations as the means for settling relevant disputes, and by emphasizing that negotiations be conducted by sovereign States directly concerned, the above-quoted provisions of the bilateral instruments and Paragraph 4 of the DOC obviously have produced the effect of excluding any means of third-party settlement. In particular, the above-mentioned Joint Statement between the People' s Republic of China and the Republic of the Philippines concerning Consultations on the South China Sea and on Other Areas of Cooperation of 10 August 1995 stipulates in Point 3 that "a gradual and progressive process of cooperation shall be adopted with a view to eventually negotiating a settlement of the bilateral disputes" . The term "eventually" in this context clearly serves to emphasize that "negotiations" is the only means the parties have chosen for dispute settlement, to the exclusion of any other means including third-party settlement procedures. Although the above-mentioned bilateral instruments and Paragraph 4 of the DOC do not use such an express phrase as "exclude other procedures of dispute settlement" , as the arbitral tribunal in the Southern Bluefin Tuna Case stated in its Award, "the absence of an express exclusion of any procedure ... is not decisive" (Australia and New Zealand v. Japan, Award on Jurisdiction and Admissibility, 4 August 2000, p.97, para. 57). As discussed earlier, in respect of disputes relating to territorial sovereignty and maritime rights, China always insists on peaceful settlement of disputes by means of negotiations between the countries directly concerned. China' s position on negotiations was made clear and well known to the Philippines and other relevant parties during the drafting and adoption of the aforementioned bilateral instruments and the DOC.

41. Consequently, with regard to all the disputes between China and the Philippines in the South China Sea, including the Philippines' claims in this arbitration, the only means of settlement as agreed by the two sides is negotiations, to the exclusion of any other means.

42. Even supposing that the Philippines' claims were concerned with the interpretation or application of the Convention, the compulsory procedures laid down in section 2 of Part XV of the Convention still could not be applied, given the agreement between China and the Philippines on settling their relevant disputes through negotiations.

43. Article 280 of the Convention states that, "Nothing in this Part impairs the right of any States Parties to agree at any time to settle a dispute between them concerning the interpretation or application of this Convention by any peaceful means of their own choice." Article 281 (1) provides that, "If the States Parties which are parties to a dispute concerning the interpretation or application of this Convention have agreed to seek settlement of the dispute by a peaceful means of their own choice, the procedures provided for in this Part apply only where no settlement has been reached by recourse to such means and the agreement between the parties does not exclude any further procedure."
