Mladen Cerovac, the president of the Croatian Competition Council, participated in the work of the international competition conference held in Belgrade on 19 April 2019. The opening word was given by the Serbian minister of finance Siniša Mali, who was followed by the president of the National Assembly Committee for the economy, regional development, trade, tourism and energy Snežana B. Petrović, the chief of the EU delegation in Serbia Sem Fabrici, and the president of the Serbian Commission for Protection of Competition Miloje Obradović. In her video message to the participants in Belgrade, the EU commissioner for competition Margrethe Vestager pointed out that all competition authorities in charge of the implementation of competition policy have a very important privilege in common: what they do has a great value for the citizens. There were two panel discussions on the agenda of the conference. The fist under the title “The role and effectiveness of competition policy and the expectations from the ECN+ Directive” and the second under the title “Effectiveness of the commitment decisions”. Mr Mladen Cerovac took part in the first panel discussion that was moderated by Nicholas Banašević from the EC delegation. Other panellists were the leading officials of the competition authorities from the region – Slovenia, Serbia, Bosnia and Herzegovina, Monte Negro, North Macedonia and Albania. The participants discussed the challenges they face in ensuring fair market competition and debated about the public perception of competition policy, the role of competition advocacy and the position of courts in strengthening of competition policy. Gianluca Sepe from the Italian competition authority moderated the second panel that dealt with commitment decisions and their effectiveness in competition law, together with the representatives from the competition authorities from Austria, Romania, Italy and Turkey.
