BEIJING (Reuters) - The Chinese foreign ministry on Monday said it firmly rejected new U.S. legislation on Tibet signed into law by President Donald Trump over the weekend. Tibet-related issues are domestic affairs, Zhao Lijian, a ministry spokesman, said at a regular media briefing. The Tibetan Policy and Support Act of 2020 calls for the establishment of a U.S. consulate in Lhasa and the absolute right of Tibetans to choose a successor to the Dalai Lama.
