This learning paper was developed to document lessons from the current Winrock counter-trafficking in persons (CTIP) programming in Thailand, as related to gender and social inclusions (GESI) and to inform future CTIP initiatives. USAID Thailand CTIP is a $10 million, five-year (2017-2022) project that aims to reduce trafficking in persons (TIP) and better protect victims’ rights in Thailand. To fulfill these objectives, the project employs a 5C strategy: community engagement, change agents, communication, collaboration, and continuity. The project partners with the private sector, government, migrant groups, at-risk communities, and the media to foster collaboration supporting the project’s main objectives. This paper is the second in a series of learning products by USAID Thailand CTIP. The learning papers aim to identify achievements, challenges, and potential risks and ensure that future activities are grounded in experience and positively impact vulnerable persons and trafficking survivors.
