Chinese leader Xi Jinping said on Tuesday that China would not build new coal-fired power projects abroad, using his address at the United Nations General Assembly to add to pledges to deal with climate change.

Xi provided no details, but depending on how the policy is implemented, the move could significantly limit the financing of coal plants in the developing world.

China has been under heavy diplomatic pressure to put an end to its coal financing overseas because it could make it easier for the world to stay on course to meet the goals of the Paris climate agreement to reduce carbon emissions.
