China on Tuesday published a pamphlet featuring standardized names of the Diaoyu Island and its affiliated islets.

The pamphlet lists the official Chinese names of 71 islands and islets, including the Diaoyu Island, Huangwei Yu (islet) and some geographic entities in their surrounding waters, according to the State Oceanic Administration (SOA).

It also details the acreage, length and width, location and diagrams, site photos and three-dimensional diagrams of the 71 islands and islets and other geographic entities.

Illustrated with documentation and historical data, the pamphlet declares that the Diaoyu Islands have been part of China's inherent territory since ancient times.

The names in the pamphlet were normalized and released earlier September by the SOA in line with the law on island protection and approved by the State Council, or Cabinet.

It will allow the public to have a deeper understanding of information related to the nation's Diaoyu Island and its affiliated islets, according to the SOA.
