International trade alone cannot bring about economic growth and prosperity in any country. There are many other factors like flexible trade policies, favorable macroeconomic scenario and political stability that need to be there to complement the gains from trade.
There are examples of countries, which have failed to reap the benefits of international trade due to lack of appropriate policy measures. The economic stagnation in the Ivory Coast during the periods of 1980s and 1990s was mainly due to absence of commensurate macroeconomic stability that in turn prevented the positive effects of international trade to trickle down the different layers of society. However, instances like this cannot stand in the way of international trade activities that are practiced across the different nations of the world.
In conclusion it can be said that, international trade leads to economic growth provided the policy measures and economic infrastructure are accommodative enough to cope with the changes in social and financial scenario that result from it.
