Other forums (APEC, NAFTA and even NAFTA) serve rather as a framework for a series of bilateral or plurilateral agreements, at least until some convergence of the regulatory procedure is achieved. The OECD could play a mediating role by helping to develop guidelines for sustainable MAs among its members and by seeking ways to maximise the involvement of developing countries in these agreements. The WTO may preside over the multilateralisation of recognition obligations if agreement on essential requirements has been reached at multilateral level, including by private bodies such as professional services. Winters, L. A., (2015). „The WTO and regional trade agreements: is it all over for multilateralism?“ EUI, RSCAS Working Document No. 2015/94.

Given that it is more or less inevitable that an EIA between the UK and the EU would eliminate some of the liberalisation of services currently available, it would not fit this definition. . .
