The Republics of Cameroon, Guyana, Malawi, and Nauru have recently joined the Biological and Toxin Weapons Convention (BWC), bringing the total number of its States Parties to 170. On March 26, 2013, Guyana deposited an instrument of ratification of the BWC with the United States, one of the three depositary states of the Convention. Cameroon (January 18), Nauru (March 5), and Malawi (April 2) have also joined the BWC this year, having deposited instruments of accession also with the United States.

The United States warmly congratulates these countries for taking this significant step. Their actions advance the BWC – one of the pillars of the global architecture against the proliferation of weapons of mass destruction – and its universality, both of which are strongly supported by the United States.
