This bill seeks to strengthen the leadership role of the United States at the Inter-American Development Bank (IDB) by directing specific actions from the U.S. Executive Director. The Secretary of the Treasury, in consultation with the Secretary of State, must instruct the Executive Director to use the U.S. voice and vote to reduce the influence of the People's Republic of China (PRC) and PRC entities in IDB activities. This includes reviewing any projects, loans, or grants involving the PRC for potential risks to U.S. national and economic security interests. Furthermore, the bill mandates voting against projects that would include participation of PRC trust funds or are deemed risky after review, and against any increase in the PRC's voting share relative to that of the United States. The legislation also encourages the U.S. Executive Director to advocate for increased procurement by entities from the United States and its partner countries , prioritizing value for money, transparency, and integrity over lowest upfront cost. Finally, it promotes collaboration between the IDB and the United States International Development Finance Corporation (DFC) on projects in borrowing member countries, requiring a DFC report on existing and potential future cooperation.
