China has 34 major ports and more than 2000 minor ports. The former are mostly sea ports (except for ports such as Shanghai, Nanjing and Jiujiang along the Yangtze and Guangzhou in the Pearl river delta) opening up to the Yellow sea (Bo Hai), Taiwan straits, Pearl river and South China Sea while the latter comprise ports that lie along the major and minor rivers of China. Most of China's major cities are also ports or are facilitated by a port nearby.
