When facing an international territorial dispute and choosing to support a party, the following factors and steps should be considered to ensure rational and fair decision-making: 1. **In-depth understanding of the background**: Have a comprehensive understanding of the historical background of the dispute, the causes of the dispute, the main interests involved, etc. Listen to the positions and views of both sides to get a full picture. 2. **International law and treaties**: Consult the international law provisions and existing international treaties related to the dispute to understand the legal basis. Support should be based on recognized international law and principles, such as the Charter of the United Nations. 3. **Multilateralism and international organizations**: Refer to the resolutions and recommendations of international organizations such as the United Nations. These organizations often promote the resolution of territorial issues through peaceful negotiations and arbitration. 4. **Diplomatic means**: Express your position through diplomatic channels and provide support in a peaceful manner to avoid exacerbating conflicts. 5. **Humanitarian concerns**: Consider the humanitarian impact that the dispute may have on the local population, support solutions that contribute to peace and stability, and minimize harm to civilians. 6. **Economic and political interests**: Objectively assess the impact that supporting a party may have on the economic and political interests of your country, and ensure that such support is in the long-term interests of your country. 7. **Regional stability**: Prioritize and promote overall peace and stability in the region, respect the sovereignty and territorial integrity of all countries. 8. **Public opinion and transparency**: Maintain a transparent decision-making process, win the support of public opinion, and ensure the legitimacy and sustainability of policy making.
