China is one of the most important factors in establishing a new global agreement on climate change, said Laurence Tubiana, France's climate change ambassador and special representative for the 21st session of the Conference of the Parties to the UN Framework Convention on Climate Change.

Tubiana made the comments in an exclusive interview with China Daily prior to French Prime Minister Manuel Valls' trip to China.

Valls said on Wednesday that Beijing has a crucial role to play in the international climate talks being held in Paris in December, adding it was the key issue up for discussion during his three-day visit.
