This legislation, known as the Taiwan International Solidarity Act, amends the existing TAIPEI Act of 2019 to reinforce United States policy concerning Taiwan's international standing. It explicitly clarifies that United Nations General Assembly Resolution 2758 (XXVI) only recognized the People's Republic of China as the representative of China, without addressing Taiwan's representation, sovereignty, or its relationship with the PRC. The bill further states that the United States opposes any initiative to change Taiwan's status without the consent of its people. The Act mandates that United States government representatives in international organizations must use their voice, vote, and influence to advocate against the People's Republic of China's attempts to distort organizational decisions, language, policies, or procedures regarding Taiwan. Additionally, it encourages U.S. allies and partners to actively oppose China's efforts to undermine Taiwan's official diplomatic relationships and its partnerships with other nations. Finally, the bill expands reporting requirements under the TAIPEI Act, mandating that future reports include detailed information on any prior or ongoing attempts by the People's Republic of China to undermine Taiwan's membership or observer status in international organizations and its relationships with other countries.
