China has made impressive efforts in combating climate change, according to the head of the European Parliament's China delegation.

Jo Leinen said the country's decision to peak emissions no later than 2030 and its readiness to take part in a five-year review process of the voluntary national emission reduction targets send a clear message to the world.

"Investments in carbon-friendly technologies can help to accelerate the decarbonization of our economies," Leinen said.
