The CBA cooperates with many international organisations and law enforcement agencies in other countries. The cooperation aims to exchange best practices, extend the knowledge on corruption, solutions and instruments applied abroad as well as to exchange information on current operational and investigative activities conducted by foreign services. In order to carry out the tasks of the Bureau, the Head of the CBA may cooperate with competent authorities and services of other countries and with international organisations. Pursuant to the Act on the CBA, such cooperation is feasible exclusively after obtaining the consent of the Prime Minister.
So far, the Bureau has obtained the consent to cooperate with 54 countries and 13 international organisations.
The Bureau established cooperation with, among others, The World Bank, which resulted in a joint publication titled: Fraud and Corruption Awareness Hand- book. A handbook for Civil Servants Involved in Public Procurement.
The CBA participated in 3 EU-funded projects under the Programme Prevention of and Fight against Crime (ISEC).
