Ending China’s Unfair Advantage Act of 2025

This bill prohibits U.S. federal funding for two international environmental agreements until China is reclassified as a "developed country" in both treaties. Specifically, it blocks funding for the Montreal Protocol (which addresses ozone-depleting substances) and the UN Climate Change Convention until China is removed from the "developing country" list under the Montreal Protocol and added to Annex I (developed country list) under the UN Climate Convention. The bill requires the President to certify these treaty changes to congressional committees before any funds can be spent on these agreements. It does not alter China's actual economic status but ties U.S. financial participation to procedural treaty revisions. The direct effect is on U.S. government funding for international environmental cooperation.
