南部战区于5月27日组织海空兵力，依法采取语音警告、电子干扰等措施驱离舰龄超20年的荷兰"德鲁伊特"号护卫舰[1]。中国海军553舰对荷兰舰载直升机进行喊话警告，喊话内容为"荷兰直升机NH-90，我是中国海军553舰，你已侵犯中华人民共和国领空，立即离开！立即离开！"[1]。中国战机同步监视[1]。
在中国领海方面，海警3305舰对菲律宾挑衅船只进行驱离[1]。由于该船只做出危险转向动作，中国海警舰艇动用高压水炮，最终迫使其举白旗[1]。
On May 27, the Southern Theater Command of the People's Liberation Army organized naval and air forces to drive away the Dutch frigate "De Ruyter," a vessel over 20 years old, employing voice warnings and electronic interference measures in accordance with law.[1] The Chinese Navy's 553 vessel issued a direct warning to the Dutch ship's helicopter, stating: "Dutch helicopter NH-90, this is Chinese Navy 553 vessel. You have violated the airspace of the People's Republic of China. Leave immediately! Leave immediately!"[1] Chinese fighter jets simultaneously monitored the operation.[1]
In coordinated action, the China Coast Guard's 3305 vessel conducted operations within Chinese territorial waters to drive away Philippine vessels engaged in provocative activities.[1] After the Philippine vessel performed dangerous maneuvers, the 3305 vessel deployed high-pressure water cannons, ultimately forcing the vessel to raise a white flag.[1]
