There are two Ideological assumptions of Regionalism: Mercantilism and Liberalism compare that two assumptions and describe it. What view based integration of Europe and what view based integration of Asia?

Mercantilism is an economic theory which holds that the prosperity of a state is dependent upon its supply of capital; that the global volume of international trade is "unchangeable;" and that one party may benefit only at the expense of another. 

Liberalism holds that state preferences, rather than state capabilities, are the primary determinant of state behavior. Unlike realism where the state is seen as a unitary actor, liberalism allows for plurality in state actions. Thus, preferences will vary from state to state, depending on factors such as culture, economic system or government type. Liberalism also holds that interaction between states is not limited to the political (high politics), but also economic (low politics) whether through commercial firms, organizations or individuals. Thus, there are plenty of opportunities for cooperation and broader notions of power, such as cultural capital (for example, the influence of American films leading to the popularity of American culture and creating a market for American exports worldwide).

Mercantilism based integration of Asia, liberalism based integration of EU
