Directs U.S. policy to mark and condemn the 1989 Tiananmen Square crackdown, to press for the release of detained protesters, to push back against PRC censorship and transnational repression, and to use diplomacy, sanctions, prosecutions, and protections for U.S. persons where appropriate. Requests that the Librarian of Congress partner with nongovernmental groups to produce in-person and online exhibits documenting the protests, survivors (including those now living in the United States), and the events’ impact on U.S.–China relations.
