A Chinese state institution warned this week that Beijing is ready to set up an air defense identification zone (ADIZ) over the contested South China Sea, giving it the authority to screen foreign aircraft. But analysts say any enforcement would anger other countries without deterring traffic.
That measure would follow a series of steps to control the movement of foreign ships in the same sea, underlining China’s intent to hold its vast maritime claims after a world court tribunal ruled in July that it lacked a legal argument.
China calls 95 percent of the sea its own and its militarization of tiny islets since 2010 has angered officials from Jakarta to Washington. Beijing reportedly toyed with the idea of an ADIZ in July after the court verdict.
