On Aug. 28, 2023, China released its standard national map which includes a 10-dash line, an extended version of its nine-dash line claim, with the 10th dash covering the eastern coast of Taiwan. This drew immediate protests from the Philippines, Vietnam, Malaysia, Indonesia, and Taiwan which saw the new Beijing map as violating their exclusive economic zones in the South China Sea (SCS). India and Russia also rejected the new map as an infringement of their respective territorial sovereignty. The nine-dash line, and its latest iteration—the 10-dash line—is being used by the Chinese Communist Party (CCP) to firm up its claim to over 90 percent of SCS.
