Conflict in international relations refers to disputes, disagreements, or confrontations between states or other actors in the international system. This can involve military conflict, economic competition, ideological disputes, or disputes over resources or territory. Conflict in international relations can be the result of competing interests, power imbalances, or differences in political or economic systems. It can also arise from a failure to communicate effectively or to find common ground. In international relations, conflicts are often resolved through diplomacy, negotiation, or the use of force, depending on the interests and motivations of the parties involved.
