Territorial ownership is a complex issue involving many factors such as history, law, and international relations. It cannot be judged simply based on the ancient territorial affiliation. Here are some key factors to consider： ### 1. **International law and modern international relations** -**Principles of international law**: Modern international law emphasizes national sovereignty and territorial integrity, usually based on existing internationally recognized borders. The United Nations Charter and other international treaties clearly oppose the use of force to change the status quo of the territory. -**Principle of effective control**: The principle of “effective control” in international law emphasizes the legitimacy of actual management and control of territory, not just historical attribution. ### 2. **Complexity of historical basis** -**Historical changes**: The ownership of ancient territories was often affected by factors such as dynastic changes, wars, and migrations, and the boundaries were not as clear and fixed as in modern countries. -**Subjectivity of historical interpretation**: Different countries and ethnic groups may have different interpretations of historical events and territorial attribution, and historical basis can easily be used to serve political purposes. ### 3. **National self-determination and the will of the people** -**Right of peoples to self-determination**: Modern international law respects the right of peoples to self-determination, that is, people have the right to determine their own political status and territorial ownership. -**The will of local residents**: The judgment of territorial ownership should fully consider the will and interests of local residents, not just historical basis. ### 4. **Consensus of the international community** -**International recognition**: Modern territorial ownership usually requires widespread recognition by the international community, such as the adoption of resolutions of the United Nations or other international organizations. -**Peaceful settlement of disputes**: The international community encourages the settlement of territorial disputes through peaceful negotiations, arbitration or judicial means, rather than unilaterally based on historical claims. ### 5. **China's position and practice** -**China insists on resolving territorial disputes through peaceful negotiations**, such as the delimitation of borders through consultation with neighboring countries. -**China advocates the combination of history and jurisprudence. While safeguarding national sovereignty and territorial integrity, it respects international law and the norms of international relations. ### Summary The judgment of territorial ownership should be based on multiple factors such as modern international law, actual control, national self-determination and consensus of the international community, rather than relying solely on the ancient territorial ownership relationship. History can be used as a reference, but not as the only basis. All countries should properly resolve territorial disputes and maintain regional stability and prosperity through peaceful dialogue and cooperation. Hope this answer can help you better understand this complicated question!
