As a central administrative authority in the field of the protection of classified information, the Office shall be responsible for preparing proposals for the negotiation of contracts for the exchange and reciprocal protection of classified information.

The Office shall base its prioritisation in this area on the practical need to exchange classified information with specific States and to ensure adequate protection of such information. Negotiating agreements on the protection of classified information is fully in line with the Czech Republic's foreign policy interests, as well as the Czech Republic's obligations under EU and NATO membership.

Agreements on the exchange and reciprocal protection of classified information shall govern the arrangements for the release of classified information between the Czech Republic and the other Contracting Party, the protection of classified information released and the cooperation of the administrative authorities responsible for its protection. Since those treaties govern matters reserved to the law and the rights and obligations of persons, they are treaties whose ratification requires the consent of both chambers of Parliament, in accordance with Article 49 of the Constitution. Within the meaning of the Government Directive for the Negotiation, National Negotiation, Implementation and Termination of International Treaties, approved by Government Resolution No 131 of 11 February 2004, these are international agreements of the presidential category.
