China will host delegates from nearly 200 countries in the northern port city of Tianjin today for a meeting aimed at getting the foundering global climate change talks back on track.
It is the first time that China - now the world's biggest producer of greenhouse gases - has hosted a formal round of climate talks in 20 years of international negotiations on the topic.
The week-long Tianjin meeting - the last official negotiations before the United Nations climate summit in Cancun, Mexico, at the end of the year - has drawn worldwide attention.
This is despite prevailing pessimism about the chances of reaching a binding deal this year on curbing the greenhouse gases that cause global warming.
Observers say the Tianjin meeting is unlikely to result in a breakthrough. Its aim, instead, is to prepare the final documents for the November 29-December 10 Cancun gathering.
Still, hundreds of non-governmental groups and media from around the world have descended on the city.
