Beijing, July 31 (IANS) China has indisputable sovereign rights over the South China Sea islands and their adjacent waters, and the country opposes any military intervention in this area, a spokesperson for China's defence ministry said Tuesday.

According to rules, a regular combat-readiness patrol system has been established in sea waters under China's jurisdiction, ministry spokesperson Geng Yansheng said at a press conference.

Geng said the system was established to maintain the country's territorial sovereignty and safeguard its maritime rights, and it is not targeting any other country or specific goals, reported Xinhua.

The Chinese navy is justified in protecting the country's interests, and it is groundless to equate such a justified action with tough foreign policy, he said.

Geng also said the establishment of the Sansha garrison in the South China Sea is responsible for defence mobilisation, militia reserves, the relationship between the garrison and local government as well as the city guard, support for the city's disaster rescue and relief work, and direct militia and reserve troops in the city of Sansha.

Geng said the establishment of the city of Sansha is a readjustment by the Chinese government to existing administrative bodies, which is an issue within China's sovereignty and unrelated to other countries.

The disputes over the South China Sea mainly revolve around the sovereignty over some islands and part of the sea delimitation in the area, Geng said.

China will continue to seek appropriate solutions through bilateral negotiations and consultations with the parties directly involved in the concerned disputes, Geng said.

China is also willing to cooperate with the Association of Southeast Asian Nations (ASEAN) in all fields, including the defense security relationship, in order to boost regional peace, stability and prosperity, Geng added.
