How did these countries solve their territorial disputes?

Countries typically resolve territorial disputes through a combination of diplomatic negotiations, international mediation, and legal adjudication. They may engage in bilateral talks to reach a mutually acceptable agreement or seek the assistance of international organizations like the United Nations. Additionally, some disputes are settled through arbitration in international courts, which provide a legal framework for resolving conflicts based on international law. Ultimately, the effectiveness of these methods depends on the willingness of the parties to compromise and collaborate.
