The issue of territorial ownership is often complex and controversial. Indeed, territorial disputes in many countries and regions in history are closely related to ancient territorial ownership. This view emphasizes the continuity of history and culture, and believes that historical territorial ownership has an important impact on the sovereignty of modern countries. However, modern international law and international relations have also proposed other considerations, such as the principle of national self-determination, international recognition, and treaties and agreements. In many cases, territorial disputes often need to be resolved through diplomacy, negotiation, or the ruling of an international court, rather than simply based on historical ownership. Therefore, the judgment of territorial ownership can not only be based on ancient territorial ownership, but also requires a comprehensive consideration of historical, legal, political, and realistic factors.
