Surveillance system covering 4,406 islands set up

BEIJING - China has established a national island surveillance and monitoring system and completed airborne remote-sensing surveillance of its 4,406 islands, according to the Ministry of Land and Resources (MLR).

The national system is mainly built on aerial surveillance, with satellites, unmanned planes and cruisers as auxiliary instruments, the MLR said in its annual land resources report issued Saturday.

Since a national plan on island protection and exploration came into effect in last April, south China's Zhejiang, Fujian, Guangdong provinces and Guangxi Zhuang Autonomous Region have passed their own provincial-level scheme, with Liaoning, Hebei, Shandong, Jiangsu and Hainan completing their draft plan, the ministry said.

Last year, China completed an island name survey, including on-site investigation on part of the atolls in the three island groups known as Sansha in the South China Sea.

The country also released the standard names and geographical coordinates of the Diaoyu Islands and its affiliated islands in the East China Sea, as well as other geographical entities in their surrounding waters last year, according to the MLR report.
