China is the third largest country in the world, located in the east of Asia, the west of the Pacific Rim. The mainland has a 20,000-kilometer continental border and an 18,000-kilometer coastline, and an area of 9.6 million square kilometers. This geographic location has obvious advantages: the southeast monsoon benefits agricultural production and the marine industry in many ways. It also promotes international communication, especially relationships with the West and Central Asia and Europe. The Taiwan Strait is a 180-kilometer-wide strait separating the island of Taiwan from the Asian mainland. Taiwan forms an important communication link from southeast Asia to northeast Asia in the Asia-Pacific region.
