Explain the second theory of international antitrust cooperation

A second theory of international antitrust cooperation is a more limited multilateral approach under which only policy cooperation is elevated to a multilateral context. Specific case enforcement would remain at the national or regional level, perhaps augmented by voluntary bilateral coordination. We can see this kind of cooperation in entities like the Organization for Economic Cooperation and Development (OECD) and International Competition Network (ICN), which serve as fora for the multilateral discussion of discrete competition policy issues. OECD and ICN work serves as guidance for members to consider and implement as desired in their own enforcement policies and techniques. They offer guidance on effective cooperation and coordination with the opportunity for convergence of different approaches should members chooses to do so.
