Lima, Dec 13 (IANS): The annual UN global climate change talks have gone into overtime as negotiators from over 190 countries tried to bridge their differences and reach a consensus early Saturday morning.

Participants at the 20th Conference of Parties (COP20) to the United Nations Framework Convention on Climate Change here have struggled to break a deadlock between the developed and developing countries over the past two weeks, aimed at working out a draft for a new international climate deal ahead of key talks in Paris in 2015, Xinhua reported.

At the opening ceremony Dec 1, Peruvian Environment Minister Manuel Pulgar-Vidal, who presided over the talks as COP20/CMP10 president, had urged participants to work in a creative way to reach global consensus in the following 12 days.

Now, he has been frustrated by the divisions between rich and poor.

"We don't want to leave Lima with empty hands. We are in a time in which we should take decisions," said Pulgar-Vidal.

The talks had been scheduled to end at 6 p.m. Friday, but ran into the small hours of Saturday.
