Jurisdiction is theoretical and practical. It is not only a symbol of sovereignty, but also defines theimage of sovereignty and determines the boundary of sovereignty application. Jurisdiction also undertakes thefunctions of combating international crimes, filling the deficiencies of traditional jurisdictional basepoints, andother functions of countermeasures and retaliation in reciprocal international relations. The different functions ofjurisdiction reflect different dimensions of international relations. The jurisdiction system established by a statein its domestic legal system reflects her position of its own sovereignty and determines the country 's perceptionof international relations and its own role in international relations. China's current jurisdiction system hasobvious conservative characteristics. With the strengthening of national power and the increase of overseasinterests that need to be protected, as well as effective response to other states' judicial interference againstChina, it is necessary for China to reform the passive jurisdiction system in the current law and transform it intoa proactive jurisdiction system.
