Question

What is the Trade bloc?

Answer 1

A trade bloc is an agreement between two governments to reduce or eliminate barriers to trade among the states whose governments are involved. A common example of such a barrier is tariffs. Trade blocs can be part of regional organizations or stand alone agreements. Successful trade blocs have four common characteristics - geographic proximity, political commitment to regional organizations, compatible or similar trading regimes and similar per capita GNP levels. The four key types of trade blocs are:

*Free trade areas

*Customs unions

*Preferential trade areas

*Common markets
