Bildt and Tóth also discussed the important role that Sweden could play in promoting the Treaty’s entry into force leading up to and during its Presidency of the European Union between July and December 2009. The EU recently reinforced its long-term support of the CTBT at a meeting of the Nuclear Nonproliferation Treaty in April-May 2008, calling on States, particularly those listed in Annex 2, to sign and ratify the Treaty without delay and without conditions. Ratification is required by all Annex 2 States before the Treaty can enter into force. The States that still need to ratify are: China, the Democratic People's Republic of Korea, Egypt, India, Indonesia, Iran, Israel, Pakistan, and the United States. The EU’s support of the CTBT is of particular importance since it includes among its members the two nuclear-weapon States, France and the United Kingdom, as well as the overwhelming majority of NATO countries.

Meetings were also held with Frank Belfrage, the State Secretary for Foreign Affairs, and Henrik Salander, Head of the Department for Disarmament and Non-proliferation at the Ministry for Foreign Affairs and Secretary-General of the Weapons of Mass Destruction Commission. In a press release issued by the Ministry for Foreign Affairs on 10 June 2008, Salander acknowledged the key role of the CTBT, “Ensuring that the Treaty enters into force is perhaps one of the most important issues on the multilateral arms control and disarmament agenda.” It was also recognized during discussions that the CTBT’s entry into force would hinder the development of new nuclear weapons and reduce the security policy significance of nuclear weapons worldwide.
