Chinese President Xi Jinping said on Saturday that the Taiwan question, democracy and human rights, China's path and system, and China's development right are four red lines for China, which must not be challenged or crossed.
is there another source that expands on exactly what this all means or are these "red lines that must not be crossed" being left intentionally vague so that when the u.s. inevitably crosses them, party leadership doesn't feel obligated to respond belligerently?
