The South China Sea is far away from the mainland, with dense routes and numerous fishing grounds. It is strongly affected by typhoons and monsoons, and shipwrecks occur frequently. In this island reef expansion, China will build civil functions and facilities, including shelter from the wind, navigation aid, search and rescue, marine meteorological observation and forecasting, fishery services and administration.

It will provide necessary assistance to ships of China, neighboring countries and countries sailing in the South China Sea. After the expansion of Nansha Island reef, the function of the reef will be multi-faceted and comprehensive. In addition to meeting the necessary military needs, it will also serve more civilian needs.

China has indisputable sovereignty over Nansha Islands and its adjacent waters. Construction is a matter within the sovereignty of China. Fair, reasonable and legal, and does not affect or target any country. This is beyond reproach.

China adheres to the path of peaceful development and pursues a defensive national defense policy. Maintaining peace and stability in the South China Sea is in the interests of China's development and security. China insists on resolving disputes with the countries directly concerned through negotiation and consultation, and on maintaining peace and stability in the South China Sea together with ASEAN countries.
