New Delhi: After attending the UN Summit for Climate Change in Copenhagen Prime Minister Manmohan Singh on Saturday left for India.

He arrived in Copenhagen to join leaders from over110 countries on Friday. He also negotiated with leaders of China,Brazil and South Africa.

The leaders of the four BASIC countries like Brazil, South Africa, China including India had a meeting with US President Barack Obama on Friday night.Obama later said that they have reached a “legally non-binding meaningful” deal to curb greenhouse gas emissions.

While talking to the reporters after the meeting Obama said that the meeting was meaningful and BASIC countries agreed to set a mitigation target to limit warming to no more than two degrees Celsius, and importantly, to take action to meet this objective consistent with science.

However according to a US official, “no country is entirely satisfied with agreement, but it is a historic step forward to be built on later”.
