RWI’s attendance at the World Human Rights Cities Forum (WHRCF) in 2016 started a long-term cooperation with the International Center at the City of Gwangju in the Republic of Korea, that hosts the Forum. Since then, RWI has been part of the international organising committee of WHRCF together with OHCHR, UNESCO, the Committee of Social Inclusion of the United Cities and Local Governments network, and the Gwangju International Centre.

The Forum gathers Human Rights Cities and local government officials from local and regional governments with an interest in human rights, along with civil society, academics and National Human Rights Institutions. In recent years, the forum has seen an increasingly high-level representation from UN Agencies. The UN Secretary General opened the forum in 2021, along with the High Commissioner for Human Rights and the Chair of UNESCO.

In addition to being part of the organising committee, RWI contributes as expert in plenary sessions and policy discussions. Further organises thematic sessions in line with topics in focus of the forum each year, and with RWI’s own focus areas, including annual policy sessions on human rights and corruption. RWI also organises a 'call for research papers' regarding human rights and local governance every year and leads a session at the forum where these papers are presented.
