The United Republic of Tanzania deposited its instrument of ratification to the Biological and Toxin Weapons Convention on 14 August 2019 becoming the 183rd State Party to the Convention. The accession of the United Republic of Tanzania to the Convention is a positive development. Other States not yet party should follow this example and join the Convention without delay.

The European Union strongly supports the strengthening of the Biological and Toxin Weapons Convention, including through full implementation of its provisions and universal adherence. All 28 EU Member States are parties to the Convention. The Convention is a key component of international efforts to prevent biological agents and toxins from ever being developed and used as weapons.
