On 15 October 2020, a regular civilian charter flight by Uni Air had to abandon its trip from the main island of Taiwan to Pratas Island when Hong Kong air traffic controllers told the captain of the aircraft that there were "dangerous activities" happening below and that the Uni Air aircraft could not enter the Hong Kong Flight Information Region (FIR). The transcript of the conversation between the pilot and air traffic control was released by the ROC Civil Aeronautics Administration. The next day, the ROC Minister of National Defense Yen Teh-fa called on China not to "disrupt the order of international aviation". On 20 October, Deputy Chief of the ROC General Staff, Lieutenant-General Li Ting-sheng (李廷盛), visited Pratas Island. He made an inspection of the living facilities of the military personnel and gave them instructions. On 26 October, the same Uni Air aircraft made the round trip flight between the main island of Taiwan and Pratas Island.
