In his state visit to USA in last week, Chinese President Xi Jinping has repeated the stance of China on the South China Sea. 

As the South China Sea issue has troubled China and other claimants as well as other external stake holders for long until now, the standing points of various parties are clearer now as time passes. 

Now it is left for the actions to speak for the words. 

Refer to the Philippinestar report on Xi Jinping's visit to USA: http://m.philstar.com/314191/show/2df0c2ec856eb8d07cf3d82281b40499/?

Since the PCA published its 6th Press Release after 2 rounds of hearing on the admissibility issue of the Philippines vs. China arbitration case over the South China Sea, there has been no reported formal response from the Chinese side. The mandate reply date in Auguest set by PCA has passed. 

More likely the case is going in the direction of an unilateral argument by the Philippines just as it was an unilateral initiation without the consent of the Chinese side. The possibility of any enforceable result is merely foreseeable.

Introduction

On Tuesday, 7 July 2015, the Arbitral Tribunal commenced the hearing on jurisdiction and admissibility in the arbitration submitted by the Republic of the Philippines against the People’s Republic of China under Annex VII to the United NationsConvention on the Law of the Sea.
The hearing will end on or before 13 July 2015 [1].

Background

The Philippines v. China arbitration commenced on 22 January 2013 when the Philippines served China with a Notification and Statement of Claim “with respect to the dispute with China over the maritime jurisdiction of the Philippines in the West Philippine Sea.” On 19 February 2013, China presented the Philippines with a diplomatic note in which it described “the Position of China on the South China  Sea  issues,”  and  rejected and  returned  the  Philippines’  Notification.   China  has  since  continued  to reiterate its position of non-acceptance of and non-participation in the arbitration. Nonetheless, the Arbitral Tribunal has noted that it remains open to China to participate in the proceedings at any time [1].
