According to international law, how should border disputes be resolved?

According to international law, border disputes should be settled through peaceful negotiation, mediation and arbitration.

1. Peace negotiation: Peace negotiation means that the two sides reach a mutually beneficial and win-win solution through negotiation, consultation and other means, through concessions and compromises by both sides. Peace negotiations usually require mutual trust, dialogue and discussion of solutions between the two parties to the dispute, which is a common way to resolve border disputes.

2. Mediation: Mediation means that a third party intervenes in a dispute and seeks a proper solution by assisting both parties to negotiate. Mediation usually requires that both parties agree to accept mediation by a third party and respect the result of mediation.

3. Arbitration: Arbitration refers to the impartial and independent adjudication of disputes by a third party. The result of arbitration is usually accepted by both parties voluntarily, which can provide a clearer legal basis for the settlement of disputes.
