[Southern Theater Command Navy Spokesperson Senior Colonel Yin Gang made a statement] On October 20, the USS Charleston littoral combat ship broke into the waters near Xianbin Reef in China's Nansha Islands without the permission of the Chinese government in the early morning of October 20. The Chinese People's Liberation Army Southern Theater Command Navy organized troops to track and monitor it in accordance with laws and regulations. China has indisputable sovereignty over the Nansha Islands and their adjacent waters. The US actions infringe on China's sovereign rights and interests, threaten maritime security, and are not conducive to regional peace and stability. The US should immediately stop relevant activities. Troops in the theater remain on high alert at all times to safeguard national sovereignty and security and maintain regional peace and stability.
