BEIJING, May 12 (Xinhua) -- A senior Chinese diplomat said on Thursday that the Arbitral Tribunal on the South China Sea had no jurisdiction and its ruling would be invalid under international law.

The tribunal misinterpreted the United Nations Convention on the Law of the Sea (UNCLOS), catered to the Philippines' claims and violated the basic principle that rulings must be based on facts and laws. Its stance is neither fair nor objective, and its decision on jurisdiction would be unconvincing, said Xu Hong, the Foreign Ministry's director general of treaties and law.

He told a press conference that an application for arbitration has to meet at least four preconditions, and the Philippines, who initiated the South China Sea arbitration against China at the Permanent Court of Arbitration in The Hague in early 2013, had not met any of them.

According to Xu, if the subject matter is beyond the scope of the UNCLOS, the dispute shall not be settled by compulsory arbitration.

For example, issues of territorial sovereignty may not be settled by compulsory arbitration. In January 23, 2013, one day after the arbitration process began, the Philippines issued a document that clearly stated that the arbitration was about sovereignty, Xu said.

Any signatory to the UNCLOS may declare that it will not accept compulsory arbitration with respect to disputes concerning maritime delimitation, historic bays or titles, military and law enforcement activities, prohibiting other UNCLOS contracting states from initiating arbitration, Xu said.

China has declared that compulsory dispute settlement procedures do not apply to maritime delimitation, therefore the Philippines is wrong to have gone to arbitration, Xu said.

If disputing parties have agreed on other means of settlement, compulsory arbitration is not an option. According to Article IV of the Declaration on the Conduct of Parties in the South China Sea (DOC), signed between China and the Association of Southeast Asian Nations (ASEAN) in 2002, all sides, including the Philippines, agreed to settle territorial disputes through negotiation and consultation by the countries directly concerned.

Parties involved in disputes are also obliged to discuss the means of settlement first, which, Xu said, the Philippines did not do.

"These preconditions bar UNCLOS contracting states from initiating arbitration," Xu said.

The tribunal in this case has failed to comply with the preconditions, and China will neither accept not recognize the decision made by the tribunal, Xu said.
