China's Xi Jinping vows to stop building new coal plants abroad

China will stop building new coal plants overseas, President Xi Jinping pledged Tuesday, a move that if fulfilled essentially would end all international financing of the dirtiest fossil fuel.

In an address to the United Nations General Assembly, Xi announced that China will not build new coal-fired power projects abroad, along with stepping up support for developing countries in developing low carbon energy, as it seeks to bolster its commitments to address climate change.
