China opposes carbon tariffs

Meanwhile, a top Chinese diplomat has warned developed countries against using climate change as an excuse to set up trade barriers. China's climate change ambassador, Yu Qingtai, says rich nations should not think that slapping carbon tariffs on imports are any substitute for reaching a deal to tackle global warming.

Graphics Yu Qingtai, Chinese Climate Change Ambassador, "We oppose the actions of any country that sets up new trade barriers under the excuse of protecting the planet."

"The attempt to resolve the issues in multilateral negotiations by taking unilateral trade steps will not succeed."
