Geological survey (28 meters) and Chinese officials (213 meters) were given separately. Secondly, the prospect of rich fishing in this area is another driving force. In 1988, the South China Sea was believed to account for 8% of the world's fishery catch, but since then it has continued to increase. Combined with the monetary benefits of surrounding natural resource reserves, China believes that the fishing profits in the South China Sea catchment area will reach US $ 1 trillion. Thirdly, the South China Sea is also a major route, one of the busiest international sea lanes in the world and has the world's busiest shipping port.
There is a communication passage in the South China Sea. The width of the northern Taiwan Strait is about 100 miles (160 kilometers) and the depth is about 230 feet (70 meters). The Luzon Strait is a major deep sea passage connecting the South China Sea and the Pacific Ocean, located between Taiwan and the Philippines, and is about 2,600 m (8,500 ft) deep. There is a shallow waterway along the eastern part of the Philippine island chain and Borneo and Sumatra south. The connection to the western Indian Ocean is a long strait of Melaka. At the narrowest point, the width is 19 miles (31 km) and the depth is about 100 feet (30 m).
A corner of the western Pacific bordering the South China Sea, South China Sea, South East Asia Continent. It is located in the Northeast Taiwan Strait (leading to the East China Sea), Taiwan and eastern Philippines, southeast and south of Borneo, the southern boundary of the Gulf of Thailand and the east coast of the Malay Peninsula, and the western and northern parts of the Asian continent. The South China Sea and East China Sea jointly formed the China Sea. The southern boundary of the South China Sea is the rise of the sea floor between Sumatra and Borneo, and the northern boundary extends from the northernmost tip of Taiwan in the Taiwan Strait to the strait of China's Fujian Province. The area is about 1,423,000 square miles (3,685,000 square kilometers) and the average depth is 3,976 feet (1,212 meters).
From the geographical point of view, the South China Sea plays an important role in the geopolitics of the Indian Ocean - the Pacific Ocean. The South China Sea border with Brunei, Cambodia, China, Indonesia, Malaysia, Philippines, Singapore, Taiwan, Thailand and Vietnam. Their recent economic growth has brought the passage of most of the world's commercial ships through these waters. The availability of transboundary sea lanes that bypass the South China Sea provides some flexibility to non-coastal countries, but Japan and South Korea provide fuel and raw materials and heavily depend on the South China Sea to serve as export routes. The South China Sea also includes a rich fishery being overfished overregulated that has been reported as having a large amount of unknown oil and gas being discovered.
