hina, the world's biggest source of planet-warming gases, has for the first time committed to an absolute target to cut its emissions, BBC reported.

In a video statement to the UN in New York, President Xi Jinping said that China would reduce its greenhouse gas emissions across the economy by 7-10% by 2035, while "striving to do better".

The announcement comes at a time the US is rolling back on its commitments, with President Donald Trump on Tuesday calling climate change a "con job".

But some critics said China's plan did not go as far as hoped to keep global climate goals in reach, according to BBC.
