China will not accept any international arbitration decision involving its territory in the South China Sea, the foreign ministry said Wednesday after the arbitration court in The Hague announced that it will deliver a final decision on July 12 over a dispute filed by the Philippines against China.

In a statement addressed to the media, The Permanent Court of Arbitration on Wednesday said it had informed the parties involved it will announce its decision in the arbitration initiated by the Philippines against China on July 12 at approximately 11 am, The Hague time.

In response, Chinese foreign ministry spokesperson Hong Lei said Wednesday night that the tribunal has no jurisdiction over the case, and the Philippines' unilateral initiation of arbitration breaches international law.

"China does not accept any means of third-party dispute settlement or any solution imposed on China," Hong said in a statement. "China will continue to work with states directly concerned to resolve the relevant disputes in the South China Sea through negotiation and consultation."

"Whatever the decision is, China will not recognize, accept or execute it," Li Kaisheng, an associate research fellow at the Institute of International Relations of the Shanghai Academy of Social Sciences, told the Global Times.

"China has a long history of de jure or legal rights in the South China Sea, and a hasty decision is a brutal intervention," Gu Xiaosong, an expert on Southeast Asian studies at the Guangxi Academy of Social Sciences told the Global Times on Wednesday, adding that the arbitration is inconsistent with international law.

Incoming Philippine President Rodrigo Duterte takes office on Thursday.

"The decision would be a challenge to Duterte's government. If the matter is not handled properly, the Sino-Philippine relations would not be fixed either," Li noted.

"Duterte will defend the Philippines on the South China Sea issue, but he will unlikely confront China," Li said.

At a Davao forum earlier this month, Duterte showed his willingness to accept China's assistance in constructing railways, telling Filipino businessmen, "I will accept the goodwill of China," according to media reports.

In 2013, the Philippines unilaterally filed compulsory arbitration against China at the Arbitration Tribunal in The Hague.
