UNITED NATIONS - China will announce its post-2020 actions on climate change as soon as possible, which will lead to "marked progress" in reducing carbon intensity, increasing the share of non-fossil fuels and raising the forest stock, said Vice-Premier Zhang Gaoli Tuesday.

Zhang, who spoke at the UN Climate Summit as Chinese President Xi Jinping's special envoy, stressed the action plan will also take the world's most populous and largest developing country to a peak in terms of its total carbon dioxide (CO2) emissions.
