On October 31, the China Coast Guard vessel 3102 turned off its AIS and entered the restricted waters of the Pratas Islands to broadcast a sovereignty claim, while the Taiwan Coast Guard's Xunhu No. 7 monitored and expelled it, broadcasting that "the Republic of China (Taiwan) and the People's Republic of China are not subordinate to each other." The two sides were approximately 1 nautical mile apart at their closest.[Taiwan Strait][China Coast Guard][Taiwan Coast Guard Administration][Pratas Islands][Cross-Strait Relations]
