BEIJING - China will not change its plan for nuclear power projects development but will learn a lesson from Japan after a massive earthquake had caused a nuclear plant malfunction, an official with China's Ministry of Environmental Protection said Saturday.

China has 13 sets of functional nuclear equipment and tests have showed all of them are safe, Zhang told a press conference on the sidelines of the national parliamentary session.

China is "keeping a close eye" on the development of the earthquake's influence on Japan's nuclear facilities, he said.

China has launched detectors in coastal cities to measure the influence of nuclear leaks from Japan and the tests have showed China has not been affected so far, the official said.
