Investment liberalization occupies an important place in the schemes of regional economic integration complementing trade liberalization to facilitate the process of restructuring of industry on more efficient lines. This restructuring enables fuller exploitation of the locational advantages or synergies between the member countries of the regional trading bloc besides facilitating businesses reaping the economies of scale and specialization. The Single Market Plan of the European Union has unleashed such a pattern of industrial restructuring not only European corporations but also the operations of foreign multinationals operating in the EU. Such restructuring also facilitates creation of supply capabilities in relatively poorer countries thus facilitating a convergence of levels of development.
