The United Nations appreciates China's sustained efforts to fight climate change, the UN climate chief said.

Patricia Espinosa, executive secretary of the United Nations Framework Convention on Climate Change, said the UN looks favorably upon China's strong commitment to transform to a greener and more sustainable development path.

"China has gradually played a more significant role leading global efforts to fight ... climate change," she said, adding that the UN expects China is able to continue playing a role in pushing the Paris pact forward.
