In international politics, regionalism refers to the process by which countries within a specific geographic area form alliances, organisations, or agreements to promote cooperation in economic, political, security, or cultural domains.

Indian policymakers have consistently recognised the strategic value of engaging with regional organisations, ensuring active participation in response to shifting geopolitical and economic trends.
