UNLOPS represents DPO, DPPA, DOS and UNOCT in Brussels and liaises on all matters related to peace and security that fall under the remit of these four Departments. As such, it provides a single UN peace and security focal point for policy discussion and operational coordination. In this regard UNLOPS engages closely with the European External Action Service (EEAS) and other EU institutions, as well as EU member state representatives. UNLOPS also engages regularly with the NATO International Secretariat.
