China said on Wednesday that it is fully within its sovereign rights to carry out activities including scientific research at Huangyan Dao, and no country has the right to interfere.

China has indisputable sovereignty over the island and its adjacent waters, Foreign Ministry spokesperson Lin Jian said at a press conference.

Lin said the South China Sea Institute of Oceanology under the Chinese Academy of Sciences has conducted a comprehensive research covering the entire area surrounding Huangyan Dao since late May. 

The scientific research, which has now been completed, helps deepen the understanding and forecast of the ecosystem of Huangyan Dao, and improve the development of ecological civilization in the South China Sea, he added.

Lin urged relevant countries to stop at once the spread of disinformation and unwarranted accusation against China, and stop making provocations and creating trouble at sea.
