Signed in 1972, the Biological and Toxin Weapons Convention (BTWC) prohibits the development, production and stockpiling of biological and toxin weapons. Currently, 173 countries are States Parties to the BTWC. Meetings of States Parties and experts are convened annually in order to discuss measures to increase biosafety, monitoring, training and exchange of experiences. In contrast to the Chemical Weapons Convention, the BTWC has no verification mechanism. Negotiations on the creation of such a mechanism failed in 2001 and were not renewed since. In the framework of the national implementation of the Convention by Austria, most recently on June 25, 2015 a seminar was held at the Diplomatic Academy Vienna on biosecurity as challenge for policy and science.
