China and India say rich countries must accelerate climate change efforts

China and India have issued a joint call for richer countries to step up their efforts to reduce global carbon emissions, ahead of this year's crucial Paris Summit.

In a rare example of cooperation between the world's first and third largest greenhouse gas emitters, a statement published during Indian prime minister Narendra Modi's visit to China calls on wealthy countries to provide finance, technology and other support to help emerging countries cut their own emissions.
