This legislation aims to prevent the District of Columbia government from forming or maintaining Sister City relationships with nations designated as foreign adversary countries . It explicitly prohibits D.C. from entering into any new agreements with jurisdictions located in these countries, defining such adversaries by referencing existing federal law. Furthermore, the bill requires the District of Columbia to terminate any existing Sister City relationships with foreign adversary countries. This termination must occur within 180 days of the Act's enactment or by the relationship's specified end date, whichever comes first. To ensure compliance, the District of Columbia will forfeit federal funds allocated for diplomatic and international community liaison services unless it certifies its adherence to these provisions to the President.
