China’s Ministry of Transport reports to have concluded a special five-day maritime traffic law enforcement and surveying operation in waters east of its Taiwan Island.
The operation was conducted in response to a joint statement issued by Japan and the Philippines on May 28, claiming that they had to decide to “commence formal negotiations to delimit the maritime boundary of the exclusive economic zone and the continental shelf between the two countries.”
Essentially, the operation was conducted in response to the unilateral decision of Japan and the Philippines to launch maritime delimitation negotiations regarding waters east of China’s Taiwan, which according to Beijing, seriously infringes upon China’s territorial sovereignty as well as maritime rights and interests.
The ministry organized the Fujian Maritime Safety Administration, Guangdong Maritime Safety Administration, the East China Sea navigation support center, and the East China Sea Rescue Bureau to carry out the operation, which included maritime patrol enforcement and hydrographic survey of key sea areas east of Taiwan island.
Maritime patrols, law enforcement, and hydrographic surveys were carried out to safeguard navigation safety and national maritime rights. China’s hydrographic survey also completed a seabed map of the area, filling a longstanding data gap and strengthening maritime governance capabilities.
The 10,000-ton maritime patrol vessel Haixun 09, the large patrol and rescue vessel Haixun 06 in the Taiwan Strait, the specialized hydrographic survey vessel Haixun 08 and the specialized rescue vessel Donghai Jiu 113 jointly carried out the operation.
A statement from the Chinese Ministry of Transport indicates that the operation covered a voyage of 1,030 nautical miles and 1,025 nautical miles of surveying.
A total of 198 passing vessels were inspected, and three instances of illegal or irregular vessel operations were corrected.
Meanwhile, it was also reported that the maritime conditions in this area are complex, posing significant challenges to vessel performance and enforcement capabilities
The ministry stated that the operation strengthened China’s capacity for maritime patrol enforcement and traffic control in the waters east of Taiwan island, and further improved maritime traffic safety assurance levels.
According to Beijing, the more external forces attempt to align the Taiwan question through alliances and militarization, the more the Chinese mainland will rely on strong law enforcement capabilities to systematize, institutionalize, and normalize management and control of the waters surrounding Taiwan Island.
