As tensions build ahead of an worldwide tribunal's ruling on Beijing's claims over the South China Sea, a veteran Chinese foreign-policy maker sent a stern warning about putting the verdict into action.

Wu Shicun, with the National Institute for South China Sea Studies, says China will continue to use peaceful means to solve any disputes and will look to speed up discussions on arranging a Code of Conduct (COC) for the region.

China's claims reach nearly to the coasts of the Philippines and some other Southeast Asian nations, and it had in recent years built giant artificial islands in the disputed areas to enforce what it says are its indisputable sovereign rights.

China hopes the United States "speaks and acts cautiously, and take no actions that harmChina's sovereignty and security interests", the statement paraphrased Wang as saying.
He said that although China has the capability to recover the islands and reefs, it has all along exercised enormous restraint and sought a peaceful settlement through talks.
"I hear The arbitration ruling will come out soon, and so be it".
China has been angered by US patrols in the South China Sea in recent months and on Tuesday launched what the Defense Ministry termed "routine" military drills there.
China has refused to take part in the case and promised to ignore all rulings that may come down, rulings that the United States of America says are mandatory and an important test of China's readiness to adhere to worldwide law.
