China will carry out a survey of its territorial islands, the State Oceanic Administration announced on July 23.

It will be the country's second integrated survey of island resources.

The survey aims to cover China's territorial islands, which number around 10,000, in five years, according to the administration.

Data on the distribution, quantity and quality of the islands' resources and the development potential of such resources, as well as the islands' major environmental and ecological conditions will be collected.

The upcoming survey is also being carried out to formulate a strategic blueprint for maritime development and social construction on the islands in its 13th Five-Year Plan (2016-20).
