One of the key responsibilities of the Security Service of Ukraine is the protection of state secrets. For this purpose, the Service facilitates the conclusion of international treaties and monitors their implementation, establishing the legal framework for the exchange and mutual protection of classified information in the context of international cooperation.

Currently, 47 interstate and intergovernmental agreements on the protection of classified information are in force for Ukraine, comprising:

• 3 agreements with 2 international organisations (NATO and the EU); and
• 44 bilateral treaties with foreign states, including:

25 with NATO member states (Albania, Bulgaria, the United Kingdom, Greece, Estonia, Spain, Italy, Latvia, Lithuania, the Netherlands, North Macedonia, Germany, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, the United States, Turkey, Finland, France, Croatia, the Czech Republic, and Sweden); and

19 with other countries (Azerbaijan, Algeria, Armenia, Vietnam, Georgia, Israel, India, Jordan, Kazakhstan, Cyprus, China, the Republic of Korea, Moldova, the United Arab Emirates, Pakistan, Tajikistan, Turkmenistan, Uzbekistan and Sri Lanka).

Three additional international treaties, with Canada, Japan and the Netherlands, are currently undergoing the domestic procedures required for their entry into force.

Work is also underway to prepare treaties with Belgium, Denmark, Iceland and Luxembourg as part of the implementation of bilateral security cooperation agreements.

The Agreement between Ukraine and the Republic of Belarus on the Mutual Protection of State Secrets ceased to have effect on 25 January 2024.
