Conference of States Parties to the Arms Trade Treaty

The Arms Trade Treaty was adopted by the UN General Assembly on 02 April 2013 and entered into force on 24 December 2014. As called for by Article 17 of the Treaty, a Conference of States Parties (CSP) was convened by the Provisional Secretariat one year after the Treaty entered into force.

  • Ambassador Jorge Lomónaco of Mexico presided over the First Conference of States Parties from 24-27 August 2015 in Mexico City, Mexico.
  • Ambassador Emmanuel E. Imohe of Nigeria presided over the Second Conference of States Parties from 22-26 August 2016, in Geneva, Switzerland.
  • Ambassador Klaus Korhonenof Finland presided over the Third Conference of States Parties from 11-15 September 2017, in Geneva, Switzerland
  • Ambassador Nobushige Takamizawa of Japan presided over the Fourth Conference of States Parties from 20-24 August 2018, in Tokyo, Japan
  • Ambassador Jānis KĀRKLIŅŠ of Latvia is presiding over the Fifth Conference of States Parties from 26-30 August 2019, in Geneva, Switzerland.

The adoption of the Arms Trade Treaty was a historic victory. However, its humanitarian impact will depend on the effectiveness of its implementation. The CSP is an important part of this, since the annual forum is where States Parties, signatories, UN bodies and civil society meet to assess and discuss implementation progress.
