China is expected to express support for Japan's sector-by-sector approach to setting goals to reduce greenhouse gas emissions, a senior Foreign Ministry official said Friday.

The announcement, to be made in a joint statement on environmental issues Tokyo and Beijing are working on, is likely to follow the bilateral summit Wednesday between Chinese President Hu Jintao and Prime Minister Yasuo Fukuda in Tokyo.

If the two leaders agree to issue the statement, it will mark a significant policy shift for China in taking a positive stance toward international efforts to reduce global warming emissions, said the official, on condition of anonymity.
