Ending China's Unfair Advantage Act of 2025

This bill prohibits U.S. federal funds from supporting two international environmental agreements until specific reclassifications of China occur. It blocks funding for the Montreal Protocol (regarding ozone-depleting substances) until China is removed from the "developing country" category in that agreement, and blocks funding for the UN Climate Change Convention until China is added to Annex I (which lists developed nations). The restrictions remain in place until the President certifies to congressional committees that these reclassifications have been made by the relevant international bodies. The bill directly affects U.S. government funding for these global environmental programs.
