Bilateral negotiations involve two parties discussing and reaching agreements on specific issues. This type of negotiation is often used in diplomatic relations, trade agreements, or conflict resolution, where each side aims to address its interests directly with the other. In contrast, multilateral negotiations include three or more parties, allowing for a broader discussion that can address complex issues affecting multiple stakeholders. These negotiations are common in international organizations like the United Nations or during global summits, where various countries collaborate to find solutions that benefit all involved.
