BALI, Indonesia: China yesterday called for joint global efforts to combat climate change under the principle of "common but differentiated responsibilities".

Xie Zhenhua, vice-minister of the National Development and Reform Commission, made the appeal at a high-level segment of the United Nations Climate Change Conference.

"Developing countries are innocent in terms of their responsibilities to the cause of climate change, but they are most vulnerable to the adverse impacts of climate change," he said.
