Conclusions – 19 October 2017 3. To consolidate and deepen this approach on all migration routes, the European Council further calls for the following:  showing full commitment to our cooperation with Turkey on migration and to support for the Western Balkans;  full and non-discriminatory implementation of the EU-Turkey Readmission Agreement with all Member States;  ensuring significantly enhanced returns through actions at both EU and Member States level, such as effective readmission agreements and arrangements; the European Border and Coast Guard Agency should be further strengthened and play an increased role in organising returns;  ensuring that CSDP missions and operations are fully staffed and that their mandates are adapted as required to assist in the fight against traffickers and smugglers networks and to help disrupting their business model; supporting the action of our partners of the G5 Sahel;  applying voluntary resettlement schemes and developing them together with international partners, in particular the UNHCR;  enhancing information and data sharing within the EU, between Member States, JHA agencies, and CSDP missions and operations, as well as with international partners; in this context, the European Council calls for the operational joint investigation teams to be extended to relevant countries;  creating and applying the necessary leverage, by using all relevant EU policies, instruments and tools, including development, trade and visa, to achieve measurable results in terms of preventing illegal migration and returning irregular migrants.
