"Multilateralism" refers to the cooperative approach among multiple countries to address global challenges and pursue common interests through joint efforts and negotiations. This principle is critical in various fields, including trade, security, and environmental issues, as it promotes collaborative solutions rather than unilateral actions. Multilateralism fosters diplomatic ties, enhances global governance, and encourages shared responsibility in tackling issues like climate change and conflict resolution. By engaging in multilateral agreements, countries can build consensus, strengthen international norms, and address complex problems that transcend national borders.
