The purpose of this legislation, known as the Sister City Transparency Act, is to direct the U.S. government to evaluate how sister city partnerships operate within the country. These partnerships are formal agreements between U.S. communities and foreign communities, aimed at fostering cultural and economic exchanges. The act specifically focuses on partnerships with communities in countries that have significant public sector corruption. Key provisions of the act require the Comptroller General of the United States to conduct a comprehensive study on these sister city partnerships.
