BEIJING - The State Oceanic Administration (SOA) on Saturday released a string of geographic coordinates of the Diaoyu Island and some of its affiliated islets, in a new move to affirm China's sovereignty.

The SOA announcement details the exact longitude and latitude of the Diaoyu Island and 70 of its affiliated islets while publishes location maps, three-dimension effect graphs and sketch maps for the Diaoyu Islands.

The announcement aims to help the public understand the information concerning the Diaoyu Island and its affiliated islets, the SOA said in a statement on its website.

The fresh statement came after the Chinese government announced on Monday the base points and baselines of the territorial waters of the Diaoyu Island and its affiliated islets, as well as the names and coordinates of 17 base points.

In its previous statements released earlier this week, the SOA said a country has the same sovereignty over its territorial sea as it does over territorial land, and such sovereignty extends to the seabed and subsoil as well as the air space above it.

Also on Thursday, China's permanent representative to the United Nations Li Baodong met with UN Secretary-General Ban Ki-moon and filed a copy of the Chinese government's Diaoyu Islands baseline announcement with the United Nations.
