Paul Meerts is an international negotiation analyst. Since 1989 he has trained thousands of diplomats, military officers and university students in more than ninety countries. In that year he became connected to the Processes of International Negotiation (PIN) Program, and became a member of its Steering Committee in 1999. Meerts has published on subjects including effective training of interstate negotiators, entrapment in negotiation, the evolution of diplomatic negotiation, order and boundaries in bargaining, and „egotiation” – the impact of the egotist negotiator on the negotiation process and its outcomes. He co-edited several PIN books and contributed to its network newsletter PINpoints for fourteen years. Having been the Director of Training and Deputy General-Director of the Netherlands Institute of International Relations „Clingendael” from 1983 till 2006, he brought PIN under its roof in January 2011. Meerts has been training civil servants of the European Commission, the Council Secretariat and the Member States inside and outside the European Diplomatic Program since it came into existence in 2001. He has been a professor at the College of Europe in Bruges since 2006. On security issues he has taught at NATO Defence College in Rome since 1989. His interest in the Comprehensive Nuclear Test-Ban Treaty stems from his training activities for the CTBTO, both at headquarters in Vienna and in the Urals.
