The purpose of this legislation, known as the Sister City Transparency Act, is to direct the Comptroller General of the United States to conduct a study on sister city partnerships in the U.S. These partnerships are formal agreements between U.S. communities and foreign communities, aimed at fostering cultural and economic ties. The study will focus particularly on partnerships involving foreign communities from countries that are perceived to have significant public sector corruption. Key provisions of this legislation include a comprehensive evaluation of sister city partnerships.
