US and China leaders in greenhouse gas emissions pledge

China and the US have unveiled new pledges on greenhouse gas emissions, as the leaders of the two countries met for talks in Beijing.

US President Barack Obama said the move is "historic", as he set a new goal of reducing US levels between 26 and 28 percent by 2025, compared with 2005 levels. 

China did not set a specific target, but said emissions would peak by 2030.

The two countries also agreed to reduce the possibility of military accidents in the air and sea.

The news came during a state visit by Mr Obama to China, which followed a major Asian regional summit.

It is the first time China, the world's biggest polluter, has set an approximate date for emissions to peak.

The two countries together produce about 45 percent of the world's carbon dioxide emissions.
