Japan remains silent on their radiation problems

China again voiced concern over the Fukushima nuclear leakage incident, and urged Japan to inform the international society of the disaster in a manner that is "timely, comprehensive, accurate and honest".

Foreign Ministry spokesman Lu Kang made the remarks at a daily news conference on Tuesday, and asked the Japanese government to "take all measures necessary to protect maritime environment".

"It's a duty the Japanese government must not shift off to explain the real situation of the Fukushima nuclear leakage incident and its impact as soon as possible and honestly," Lu said.

Lu's remarks came after news reports that the Japanese government lifted the evacuation directive for most of the areas of a Fukushima village on Sunday.

The whole village had been evacuated due to the nuclear leakage of the Fukushima Daiichi Nuclear Power Plant that started in March 2011, after the plant was damaged by a great earthquake and tsunami.

According to The Asahi Shimbun, the Tokyo Electric Power Company that runs the plant failed to officially acknowledge until in May 2011 that reactor meltdowns occurred during the accident.

Following the March 2011 great earthquake and Tsunami in Japan, China's Foreign Ministry issued a safety warning, advising against Chinese people to travel to the disaster-areas including Fukushima.

"The warning is still valid," Lu said on Tuesday.

"The impact the nuclear leakage caused on the environment, ecology and food safety is not only limited in Japan. Thus I think the Japanese government should provide a responsible explanation to the Japanese people, the neighboring countries, as well as the international community as soon as possible."
