Interestingly, the marines are not stationed where they could be used for an invasion of Taiwan, but in the south, where they can grab disputed islands. While these islands, which control fishing and potential oil fields, are considered disputed, China has already laid claim to some of them by force. In 1974, China fought a naval battle with the Vietnam off the Paracel islands. In 1988, China and Vietnam fought another naval battle, off the Spratly islands. Both of these battles were followed by Chinese troops establishing garrisons on some of the islands. In 1992, Chinese marines landed on Da Lac reef, in the Spratly Islands. In 1995, Chinese marines occupied Mischief Reef, which was claimed by the Philippines.
The Chinese marines are trained and equipped for raiding, not for large scale landings against a defended shore. The latter task is apparently left to army divisions that have been drilled on how to get on, and off, amphibious ships. While the Chinese marines might play a part in a Taiwan invasion, their full time job appears to be in the South China Sea, where the Chinese stand ready to grab more islands, if the economic advantages seem high enough.Military news
See, economic development of China is okay,but military build-up is a threat to Japan.
