MERCOSUR - The Southern Common Market is one of the world's leading economic blocs and its fifth-largest economy. It is composed by five countries nominates as “members”. Two more may be added in 2017 still. Almost 300 Million people live in the country members associated with GDP of more than 3.4 Trillion. The ambition to grow and extend its integration to other countries in comparison to European Union - EU is a dream deserved by all mostly key country such as Brazil, the largest country by far among the country members. EU recently celebrated its’ 60th anniversary of creation; Mercosur is still young with no more than 20 years of existence. Still lots to learn in regards to countries interests; standardization of regulations to ease the process in the promising land of multiracial people, unstable political environment but still a promising economic power.
