The ECN is a regional integration arrangement consisting of the competition agencies of the EU member States, including Romania and the European Commission who are enabled to co-operate to apply the same competition rules, namely those in the EU Treaty with detailed provisions on co-operation between them in application provided by EC Council Regulation 1/2003, (known as the ‘modernisation Regulation’) and EC Council Regulation no. 139/2004. In virtue of this Regulation, all ECN members are allowed to exchange information, including confidential information, for the purpose of applying the EC competition rules.  Practical aspects of cooperation within ECN: 1. Starting with 2016, Romanian Competition Council (hereinafter referred to as RCC) has started to actively assist the DG Competition from the European Commission in the inspections conducted under art. 20 of the Regulation 1/2003. 2. The RCC asked for the assistance of another competition authority for the first time in the analysis of an anti-competitive practice in 2017. More specifically, RCC carried out a dawn raid on the territory of the UK, EU Member State at that time, with the assistance of the UK Competition and Markets Authority. The aim was to collect information in a currently ongoing investigation on an alleged agreement within the aviation insurance market. The Competition and Markets Authority of the United Kingdom assisted the Romanian Competition Council, but it has not itself carried out an investigation into this matter. 3. In 2018, the RCC has carried out dawn raids in the EU countries Belgium and Italy as part of the investigation into a potential cartel on the immunoglobulin market finalized with high fines issued by the RCC in 2021. The national competition authorities in Belgium and Italy performed dawn raids on their territories at the request of the RCC, which also assisted through its inspectors.
