Almost 200 nations sought on Wednesday to break a deadlock between rich and poor on steps to fight global warming and avert a new, damaging setback after they failed to agree a U.N. treaty last year in Copenhagen.
Several environment ministers said that failure at the talks in Mexico could undermine faith in the ability of the United Nations to tackle global problems in the 21st century as power shifts toward emerging nations led by China and India.
“I think that what is at stake here is also multilateralism,” said European Climate Commissioner Connie Hedegaard. “It’s absolutely crucial that this process, which is the only one we have … can prove that it can deliver results.”
