Despite the popular image of international borders as clear, one-dimensional lines separating sovereign states, these boundaries are not always set in stone. Conflicts over disputed territories can range from minor diplomatic disagreements to full-scale war, and they can affect the political relations, economic stability and civilian populations of the contested areas. Border disputes can be resolved through negotiation, mediation or arbitration. However, these processes can be complicated by the fact that the treaties establishing the original borders often include vague or conflicting language, leaving a wide margin for interpretation. The redrawing of borders can also be influenced by cultural and ethnic nationalism, as well as the desire to acquire natural resources.
In some cases, a dispute can be settled through a mutual agreement between the parties involved, but this solution relies on both sides following their commitments in the future, which can be difficult to ensure. International arbitration is frequently the preferred method of resolution because of its neutrality, flexibility and relative speed. Other options are legal proceedings in national courts, but this is not always possible or effective given that there may be differences in jurisdictions and laws.
Disputes can arise from any number of factors, but they are often related to the ownership and control of territorial resources such as rivers, fertile farmland or minerals. These conflicts can also be fueled by politics, domestic or foreign policies and geopolitical competition. In some cases, border disputes can even evolve into geopolitical games of big-power rivalry and confrontation.
