No, the marine police belong to the government department and the police force and have the ability to enforce the law. Marine police vessels are mainly equipped with water cannons, and the crew hardly carry deadly weapons. Warships belong to the army and are a symbol of national sovereignty. The warship carries offensive and defensive weapons and has the ability to enforce the military. If a warship is sent to the disputed area, it will "trouble" the other navy and air force to help "escort", but if it is a marine police, it will be driven away. However, by removing its offensive weapons and spraying the Shanghai police logo, the warship is a marine police ship. Therefore, there is no difference in tonnage between warships and marine police vessels, only the difference in tasks. The Japanese define the helicopter carrier as amphibious assault ship, which is intended to bypass international supervision. This is a mean person's practice. We are doing it on a large scale. We are not Japan!
