The main purpose of this legislation is to prevent the use of U.S. taxpayer funds for animal experimentation in laboratories located in countries considered adversarial to the United States. The goal is to ensure that American resources are not used to support research practices in nations that may pose risks to U.S. interests or values. Key provisions of the legislation include a ban on the Secretary of Health and Human Services from conducting or funding any biomedical research involving vertebrate animals in specified foreign countries.
