The actions of the Vietnamese authorities are a serious provocation. The harassment by Vietnamese ships of the Chinese oil rig operating normally within the waters under China's jurisdiction infringes upon China's exclusive sovereign rights and jurisdiction over the natural resources within waters under China's jurisdiction. Vietnam should be held accountable for the consequences of its actions, which are in violation of international law, and China certainly has the right to take countermeasures in accordance with international law.

The Convention for the Suppression of Unlawful Acts against the Safety of Maritime Navigation and the Protocol for the Suppression of Unlawful Acts against the Safety of Fixed Platforms Located on the Continental Shelf, two documents passed by the International Maritime Organization in 1988, formally came into effect on March 1, 1992. China and Vietnam have both ratified and are party to these two international conventions. As stipulated by the two documents, China has legitimate rights to exercise its jurisdiction and impose some sanctions, against any country whose activities endanger the safety of navigation and its fixed platforms on its continental shelf.

By mobilizing armed vessels to ram Chinese ships in waters only 17 miles away from China's Zhongjian Island, Vietnam has made clear its intention of provoking a head-on clash with China and exerting pressure on China. With such reckless and risk-taking behavior, Vietnam has turned a blind eye to the overall picture of Sino-Vietnamese relations and ignored the ongoing efforts made by both countries to create a good atmosphere and environment for all-round cooperation, and seriously jeopardized bilateral mutual trust.

The Vietnamese attempt to force China into giving up its legitimate rights and interests by escalating regional tension is both dangerous and futile. On the contrary, Hanoi will put itself in a dilemma that it cannot handle.
