THE HAGUE, July 15 (Xinhua) — The International Court of Justice (ICJ) on Thursday denied its involvement in the South China Sea arbitration.

"There is indeed a confusion," Andrey Poskakukhin, head of the ICJ's Information Department, told Xinhua in a telephone interview. "We have made it clear on our website we do not have anything to do with this case."

A statement regarding the case has appeared on the ICJ's official website since Wednesday afternoon to clarify that it did not participate in the case.

The ICJ "wishes to draw the attention of the media and the public to the fact that the Award in the South China Sea Arbitration was issued by an Arbitral Tribunal acting with the secretarial assistance of the Permanent Court of Arbitration (PCA)," said the statement.

"The ICJ, which is a totally distinct institution, has had no involvement in the above mentioned case and, for that reason, there is no information about it on the ICJ's website," it said.

The clarification by the ICJ came one day after an ad hoc tribunal, set up at the unilateral request of the former Philippine government, issued an ill-founded award, denying China's long-standing historic rights in the South China Sea.

The Chinese government said that China will not accept any proposition or action based on the decision made by the law-abusing tribunal, which exceeded its power to rule on a case that it did not have jurisdiction over.

However, reports of some media, including some popular media in the United States and Europe, referred to the tribunal as a "UN-backed tribunal," or even "UN tribunal," causing confusion among the public.

UN spokesperson Stephane Dujarric on Thursday told a news briefing that the arbitral tribunal "is not something that involves the Secretary-General."

Established in June 1945, the ICJ is the principal judicial organ of the United Nations, also known as "the world court" or "the UN court," while the PCA, on the other hand, is a permanent framework established in 1899.

The ad hoc tribunal handling the South China Sea arbitration does not belong to the PCA and only enjoys the secretarial services offered by the PCA, which includes helping appoint experts, publish information and press releases, organize tribunals in The Hague and pay arbitrators and other staff for their services.

However, the tribunal has relations with the International Tribunal for the Law of the Sea (ITLOS), as most of its members were picked by Shunji Yanai, then ITLOS president and former Japanese ambassador to the United States.
