The United States must meet its international obligations on climate change and do more than "shout slogans", China's foreign ministry spokesman Zhao Lijian said on Friday following a U.S. Supreme Court ruling limiting Washington's ability to cut power sector emissions.
The Supreme Court voted to constrain the authority of the U.S.'s Environmental Protection Agency to regulate greenhouse gas emissions from existing coal- and gas-fired power plants under the Clean Air Act, sparking dismay among environmentalists.
