Article 6 of the Criminal Law clearly stipulates that this law shall be applicable to all crimes committed within the territory of People's Republic of China (PRC), except as otherwise provided by law. But in international law, China's formal jurisdiction is based on the principles of territorial jurisdiction and protective jurisdiction. In view of the chaos in the port, China implements exclusive jurisdiction. The same is true of civil cases. China has exclusive jurisdiction over civil disputes or parking fees caused by port infringement. However, it should be noted that if a case or civil dispute occurs on board a ship, I mean that jurisdiction can only be exercised under certain circumstances, that is, the victim is a coastal state or its nationals, and the coastal state will only exercise jurisdiction when the case is serious or the consul or captain of the flag state requests it. Another point is that all countries can exercise jurisdiction over international crimes, such as piracy and drug trafficking, no matter where they are.
