Denmark has not been allowed to participate in the overhaul of the 2016 Europol Regulation because it disconnects from the area of freedom, security and justice. In a referendum in December 2015, she opposed the transformation of her opt-out into a case-by-case opt-in, which would have allowed her to participate in the new regulation and remain a member of Europol. However, Denmark and the European Union agreed on a cooperation agreement in December 2016. The agreement was adopted by the European Parliament and the Danish Parliament on 27 April 2017 and signed on 29 April 2017, two days before Denmark was cut off from the Agency.    Rob Wainwright, Director of Europol, said: “This agreement will establish cooperative relations between Europol and Ukraine to help EU Member States and Ukraine prevent and combat serious and organised crime, terrorism and other forms of international crime. It will facilitate effective operational cooperation between Europol and Ukrainian law enforcement agencies and make the EU and Ukraine safer. Ukrainian Interior Minister Arsen Avakov and Europol Director Rob Wainwright today signed an operational and strategic agreement to strengthen cooperation in the fight against cross-border criminal activity. Aware of the urgent problems posed by international organized crime, particularly terrorism, and other serious crimes, the agreement allows the exchange of information, including the personal data of alleged perpetrators, and joint planning of operational activities. Ukraine and Europol today signed an agreement to strengthen cooperation in the fight against cross-border criminal activities. The text of the cooperation agreement between Europol and Ukraine was approved by the Council of the European Union and supported by the European Parliament and signed in The Hague on 14 December. The Director of Europol is able to conclude agreements for Europol with other countries and international organisations. Since September 2017, Europol has been cooperating operationally with Albania, Australia, Bosnia and Herzegovina, Canada, Denmark, Colombia, Georgia, Iceland, Liechtenstein, Moldova, Monaco, Montenegro, Northern Macedonia, Norway, Serbia, Switzerland, Ukraine and the United States of America, as well as Interpol.
    Similarly, the Agency has strategic agreements with Brazil, China, Russia, Turkey, the United Nations Office on Drugs and Crime (UNODC) and the World Customs Organization (WCO).    The signing of the Operational and Strategic Cooperation Agreement concludes the successful negotiations between Ukraine and Europol on effective cooperation in the fight against serious and organised crime. After the agreement enters into force, this new level of cooperation will be important in the fight against priority areas of crime affecting both the European Union and Ukraine, such as drug trafficking, counterfeiting and illegal immigration.
