Issues regarding territorial disputes and territorial ownership are often very complex and sensitive. This involves factors such as history, law, politics, culture and international relations. The following factors often affect the judgment of territorial ownership: 1. **Historical background**: Know the history of the area, including previous national borders, treaties and wars. 2. **International treaties and agreements**: Many territorial issues may have been resolved through international treaties or agreements, which can provide a legal basis. 3. **International law**: International law, such as the Charter of the United Nations and the judgments of the International Court of Justice, may provide some guiding principles. 4. **Actual control**: Who actually controls the area is sometimes more decisive than legal ownership in the short term. 5. **International recognition**: Recognition by other countries or international organizations may affect the legal status of a region. 6. **Cultural and demographic factors**: The ethnic and cultural background of the residents of the area may also be used as a reason to claim territory. Resolving territorial disputes usually requires reaching a consensus through bilateral negotiations, international mediation or arbitration. In any case, these issues are usually not simply resolved through data or unilateral information. If accurate information or judgment is needed, it is usually recommended to consult international law experts or scholars in related fields.
