The Commission and the Member States concerned shall, in a manner commensurate to their respective responsibilities, foster synergies and ensure effective coordination between the Facility and other Union programmes and instruments, including the Technical Support Instrument, and in particular with measures financed by the Union funds. For that purpose, they shall:

(a) ensure complementarity, synergy, coherence and consistency among different instruments at Union, national and, where appropriate, regional levels, in particular in relation to measures financed by Union funds, both in the planning phase and during implementation;

(b) optimise mechanisms for coordination to avoid duplication of effort; and

(c) ensure close cooperation between those responsible for implementation and control at Union, national and, where appropriate, regional levels to achieve the objectives of the Facility.
