The Department of Foreign Affairs of the Philippines issued a statement (30 April 2020) contesting the so-called districts of “Nansha” and “Xisha” under the supposed administrative jurisdiction of its self-declared “Sansha City” announced on 18 April 2020 by the People’s Republic of China. According to this announcement by China, “the Xisha District of Sansha City has jurisdiction over the islands and reefs of the Xisha Islands and its sea areas, and is in charge of the islands and reefs of the Zhongsha Islands and its sea areas”. The statement from the Philippines is available here.
The United States of America also issued a statement (22 April 2020) describing China’s announcement as a “new unilateral announcement of administrative districts over disputed islands and maritime areas in the South China Sea”.
