Through five so-called EU Joint Actions adopted in the framework of the European Union’s Common Foreign and Security Policy, Sweden has made substantial voluntary contributions in support of the CTBTO’s work in areas such as training, verification regime enhancement and technical assistance to third countries. Both the 2012 EU Joint Action and the preceding one in 2010 amounted to over € 5 million.

Ambassador Hans Lundborg, Permanent Representative to the United Nations in Vienna, was chairperson of the CTBTO Preparatory Commission in 2008, see CTBTO press release.

Sweden was the 22nd State to ratify the CTBT, see CTBTO press release.


"With the near completion of the International Monitoring System (IMS) undetected testing is virtually impossible. The system has proven itself on several occasions, including the announced North Korea tests in recent years. It has clearly been demonstrated that the CTBT will work once in place. Now, what remains is the political will to put it there."
