About 25,000 participants from governments, businesses, non-governmental organizations and research institutions from 194 countries gathered in Cancun.

The Cancun conference is another important step for the international community to advance the "Bali Road Map" negotiations after the UN Climate Change Conference in Copenhagen last year, which failed to reach a legally binding treaty for the years beyond 2012.

The parties will try to reach a legally binding treaty to replace the Kyoto Protocol at Cancun Conference, although the chance is slim.

They will also pay attention to the issues including green technology transfer and additional financial support to developing countries.
