This bill, titled the Taiwan International Solidarity Act, amends the existing Taiwan Allies International Protection and Enhancement Initiative (TAIPEI) Act of 2019. It clarifies that United Nations General Assembly Resolution 2758 (XXVI) only recognized the People's Republic of China as the lawful representative of China, but did not address Taiwan's representation, sovereignty, or the relationship between the PRC and Taiwan. The United States explicitly opposes any initiative that seeks to alter Taiwan's status without the consent of its people. The legislation mandates that U.S. representatives in international organizations use their influence to advocate against the People's Republic of China's efforts to distort organizational decisions, language, policies, or procedures concerning Taiwan. Furthermore, it encourages U.S. allies and partners to actively oppose the PRC's attempts to undermine Taiwan's official diplomatic relationships and partnerships globally. The bill also expands reporting requirements under the TAIPEI Act to include detailed information on the PRC's ongoing efforts to undermine Taiwan's international membership, observer status, and relationships with other countries.
