President Karol Nawrocki has signed legislation ratifying a comprehensive security agreement between Poland and Ukraine, replacing 1999 regulations to address modern risks including sabotage, cyber threats, and terrorism.
Updating the Legal Framework
President Nawrocki signed the act on Thursday, April 17, 2026, granting ratification for the intergovernmental agreement initially signed in Lviv on December 11, 2025. This treaty replaces the previous 1999 framework that focused primarily on organized crime.
The new regulations are designed to adapt bilateral cooperation to contemporary security challenges, including the ongoing war, migration pressures, and active sabotage operations.
Expanded Operational Powers
The agreement broadens the scope of cooperation beyond organized crime to cover all criminal acts defined by both nations’ laws, as well as specific offenses. It authorizes new forms of operational activity, such as controlled deliveries and the exchange of liaison officers.
The catalog of state bodies permitted to participate in this cooperation has been expanded, with a particular focus on border services and the protection of critical infrastructure.
Data Protection and Security Coordination
The document formalizes data protection protocols in accordance with EU regulations. It acknowledges that previous cooperation mechanisms were insufficient to address current security concerns.
During the signing in Lviv, Polish Interior Minister Marcin Kierwiński and Ukrainian Interior Minister Ihor Kłymenko emphasized that the pact establishes a framework for preventing drone-related threats, protecting essential infrastructure, and countering Russian disinformation campaigns.
The ratification act is scheduled to enter into force 14 days after its official publication.
