PRIF constantly works to further enhance its international visibility, broadening the scope of its research findings and policy advice, and intensifying synergies and scholarly exchanges with the leading international peace research institutes. 

For decades, PRIF has enjoyed successful cooperation with the Peace Studies Program of Cornell University, the James Martin Center of the Monterey Institute of International Studies, and European peace research institutes. Joint projects and temporary residencies for researchers are important pillars of PRIF’s cooperation with such international research facilities. 

International networking is a key element in the promotion of young researchers. In recognition of this, PRIF has come together with the Otto Suhr Institute of the Freie Universität Berlin and the Hebrew University Jerusalem to jointly establish an exchange program for doctoral students.

PRIF is currently a member of the EU Non-Proliferation Consortium, along with other leading European think tanks. The consortium advises the European Union on issues regarding the non-proliferation of weapons of mass destruction and the control of small arms.

PRIF is also involved in the Jean Monnet Network “PACO - Interparliamentary Cooperation in the EU's External Action - Parliamentary Scrutiny and Diplomacy in the EU and Beyond”. PACO connects researchers at seven institutes in Europe who address the role of parliaments in the foreign relations of the EU, supporting research cooperation, teaching activities and professional training among them. PACO is funded by the European Commission.
