In 2022, Russia invoked Articles V and VI of the Biological and Toxin Weapons Convention (BTWC), requesting a formal meeting to discuss, and subsequent investigation of, alleged U.S.-funded biological weapons laboratories in Ukraine. Such allegations have been dismissed as false by scholars and diplomats alike, many of whom have argued that Russia's actions represented an abuse of BTWC provisions and risked undermining the Convention. However, few scholars have assessed the implications of Russia's ongoing efforts to level false allegations in BTWC meetings following the Article V and VI procedures. Using mixed-methods analysis of BTWC meeting recordings, transcripts, and documents, we assessed the volume, consequences, and framing of Russian false allegations at the BTWC Ninth Review Conference. Analysis revealed that discussion of Russian allegations took over three hours and contributed to a stunted Final Document. Additional potential consequences are discussed, including increased division among states parties and the erosion of nonproliferation norms.
