<![CDATA[Sweden's commitment to gender equality in its foreign policy was strengthened through the declaration of the Feminist Foreign Policy (FFP) in 2014. This commitment became the basis for Sweden's advocacy of the Women, Peace and Security (WPS) agenda at the United Nations Security Council (UNSC), particularly during its tenure as a non-permanent member in 2017–2018. As a middle power, Sweden utilized multilateral diplomacy to promote the mainstreaming of gender perspectives in the international peace and security agenda. This research employs a qualitative approach with a descriptive method through document analysis of UNSC resolutions, UN Secretary-General reports, Swedish official statements, and related foreign policy documents, applying the Multi-Track Diplomacy framework to map Sweden's strategies through formal (Track I) and non-formal (Track II) channels. The findings show that Sweden's advocacy included participation in the formulation and voting of WPS resolutions, use of the UNSC presidency, gender-sensitive statements, Arria Formula Meetings, partnerships with civil society organizations, coalition-building with like-minded states, and financial support through Sida and the Folke Bernadotte Academy. These strategies contributed to increased integration of gender perspectives in UNSC resolutions, growth in the adoption of National Action Plans on WPS, and strengthening of WPS institutions, although Sweden's advocacy continued to face P5 geopolitical dynamics, contradictions in arms-export policy, and neo-colonial feminism critiques. Sweden's diplomacy confirms that a middle power can influence the development of international norms through legitimacy, coalition-building, and adaptive diplomatic strategy.
