of
USNS Impeccable in international waters, 8 March 2009 China's maritime militia was established after the
Chinese Communist Party (CCP) won the
Chinese Civil War and forced the
Kuomintang (KMT) to flee the mainland to Taiwan. The newly consolidated communist government needed to augment their maritime defenses against the nationalist forces, which had retreated offshore and remained entrenched on a number of coastal islands. Therefore, the concept of
people's war was applied to the sea with fishermen and other nautical laborers being drafted into a maritime militia. The nationalists had maintained a maritime militia during their time in power, but the communist government preferred to craft theirs anew given their suspicion of organizations created by the nationalists. The CCP also instituted a national-level maritime militia command to unite the local militias, something the KMT had never done. In the early 1950s, the Bureau of Aquatic Products played a key role in institutionalizing and strengthening the maritime militia as it collectivized local fisheries. Bureau of Aquatic Products leaders were also generally former high-ranking PLAN officers which lead to close relations between the organizations. The formation of the maritime militia was influenced by the Soviet "Young School" of military theory, which emphasized coastal defense over naval power projection for nascent communist powers. The maritime militia was particularly important from the 1950s through the 1970s, during which it had a significant role in national defense and territorial assertion. In the 1960s and 1970s, the PLAN established maritime militia schools near the three main fleet headquarters of
Qingdao,
Shanghai, and
Guangzhou. China's fishing fleet was being downsized until 2008, when maritime militia funding lead instead to an expansion. This expansion has led to an increase in
illegal, unreported and unregulated fishing. In 2019, the United States issued a warning to China over aggressive and unsafe action by their Coast Guard and maritime militia. The maritime militia is believed to be behind a number of incidents in the South China Sea where high powered lasers were pointed at the cockpits of aircraft. This includes an attack against a
Royal Australian Navy helicopter. In 2022, satellite images showed that more than a hundred militia vessels operated in the South China Sea on a daily basis. The number of vessels peaked in July 2022, when around 400 militia vessels were deployed in the South China Sea. The movement and the observed behavior of the militia vessels remained consistent over the years. In 2023, militia activity around key features in the South China Sea averaged 195 vessels per day, representing a 35 percent increase from the previous year. In June, 2025, a Chinese maritime militia vessel with hull number 16838 ran aground near
Pag-asa Island in the
West Philippine Sea and, for the first time on record, deployed a parachute anchor that dragged across a coral reef. The anchor caused significant damage to 307 square meters of coral, marking the first documented case of a Chinese militia vessel inflicting reef destruction through this method within Philippine waters. The incident highlighted growing concerns over the environmental impact of maritime militia operations in ecologically protected zones. ==Structure and characteristics==
