China and the United States have agreed to increase their cooperation in cutting methane emissions and other efforts to combat climate change.
The world's two largest greenhouse gas emitters announced a joint declaration on Wednesday in response to the talks at the United Nations' COP26 climate conference.
Methane leaks are believed to have greenhouse gas effects 20 times more harmful than carbon dioxide emissions.
Earlier this month, the United States announced an action plan on reducing methane emissions.
In the joint statement, China also declares it aims to compile bold and comprehensive plans.
