Xie Zhenhua, who led China's delegation to fractious negotiations in Copenhagen last year, said the only target for a December gathering in coastal Cancun city was a "positive result."
Top European and U.N. officials had already all but ruled out a deal this year, but Xie's comments are the first time the world's number one emitter has confirmed it also does not expect to seal a new pact in 2010.
"Everyone is now taking pragmatic measures, and working hard in a positive manner, in order that we can achieve a legally binding agreement at next year's meeting in South Africa," Xie told a Sino-European political forum.
