TOKYO - China, one of the world's largest emitters of greenhouse gases, will take part in negotiations on a framework for limiting global warming after 2012, the Japanese Yomiuri Shimbun said on Saturday.

On Friday, climate experts issued their starkest warning yet about the impact of global warming, which is widely blamed on emissions of greenhouse gases from burning fossil fuels.

China is not part of the U.N. Kyoto Protocol, the main plan for capping greenhouse gas emissions, which is in effect up to 2012.

The Yomiuri reported that Beijing would express its intention to take part in talks on setting up a post-Kyoto framework in a joint statement to be issued during Premier Wen Jiabao's visit to Japan from Wednesday.

In addition, Japan would announce that it would assist China with energy-saving technology, the newspaper added.

Experts have long said that if any post-Kyoto agreement is to succeed, major emitters such as the United States, China and India need to be on board.

China is set to unveil its national plan to tackle global warming later this month, and a top climate change official said in March that the plan would include policies for cutting back greenhouse gases but declined to comment on whether it would give an overall national target.
