A part of the Pacific Ocean, the South China Sea is a marginal sea, encompassing an area from the Singapore and Malacca Straits to the Strait of Taiwan of around 3,500,000 square kilometres. The area's importance largely results from one-third of the world's shipping transiting through its waters, and that it is believed to hold huge oil and gas reserves beneath its seabed. The sea and its mostly uninhabited islands are subject to competing claims of sovereignty by several countries. Learn more about South China Sea, its significance in world trade, the energy reserves it contains and the tense territorial disputes over its control in the following pages.
