China has indisputable sovereignty over islands in the South China Sea and their adjacent waters, a Foreign Ministry spokesperson said at a press conference Tuesday.

Satellite images recently released by the Chinese media showed that Vietnam attempted to construct two artificial islands in part of the South China Sea that is claimed by China.

China hopes that disputes with neighboring countries over the Nansha Islands should be resolved through bilateral and friendly consultations, according to Lu Kang, a spokesperson of China's Ministry of Foreign Affairs.

In response to the amendment of Sanya's Flight Information Area by International Civil Aviation Organization's (ICAO) as per Vietnam's request, Lu pointed out that markers on the relevant aeronautical chart are to facilitate effective air control and flight guidance and maintain security and order of international civil air transport.

Lu hoped relevant party would not politicize the matter.
