China hopes the Japanese government will act in a responsible manner and take concrete measures to tackle excessive radiation at the Fukushima nuclear plant, Foreign Ministry spokesman Lu Kang said on Monday.

After analyzing images taken by a manually operated camera that probed the deepest point yet within the reactor, Tokyo Electric Power Co said on Thursday that radiation levels inside the plant's No 2 reactor were estimated at 530 sieverts per hour at one spot, hitting a record high.

The 2011 Fukushima nuclear disaster, triggered by a massive undersea earthquake and tsunami, sent three reactors into meltdown at the Fukushima plant in the worst such accident since Chernobyl in 1986.

We have "asked many times for the Japanese government to handle it in a timely and proper" fashion, Lu told a daily press conference.

Lu said that any government, that wants to be responsible, will consider the accident's impact on the marine environment, food safety and human health.

"We hope the Japanese government can take concrete measures to counteract the effects caused by the accident. This is not only responsible to its own people, but also to people in neighboring countries," he said.

Lu also said that the Foreign Ministry has released related alerts, and he believes "Chinese citizens will properly arrange their trips and take proper precautions".
