The dominant free trade model has been heavily criticised for preventing "developing" countries from introducing economic reforms suitable to their own growth and poverty-reduction needs.
By imposing a "one size fits all" approach, states in the global South have been greatly disadvantaged.
As Britain and the US industrialised, they freely applied tariffs and other economic policies to protect strategic industrial sectors.
Today, these options have been greatly curtailed.
As Ha-Joon Chang, the Cambridge economist, cogently argues, despite "developed" countries having adopted interventionist economic policies to facilitate their own growth, they now prevent "developing" states from adopting similar measures.
In this respect, the WTO, the foremost international trading body, has frequently been criticised. Established with the principal objective of liberalising and promoting free trade to foster global economic growth and development, the actual contribution of the WTO to increased trade is debatable.
The American economist Andrew Rose, a free-trade advocate writes: Membership in the GATT/WTO is not associated with enhanced trade, once standard factors have been taken into account. To be more precise, countries acceding or belonging to the GATT/WTO do not have significantly different trade patterns than non-members."
Many in the Southern Hemisphere (South) believe the WTO acts as a lever for the Northern Hemisphere (North) to increase its economic influence. Although constantly demanding market liberalisation, the North is slow to do so itself.
Perhaps most damning of all is the fact that the majority of trade agreements, both inside and outside the WTO, have relatively little to do with the promotion of free trade but instead are more concerned with the imposition of rules and the creation of a homogenous global marketplace, where the South is at a disadvantage.
The real problem is therefore not the South's lack of integration into the world market but rather the terms under which it has been integrated.
Rather than helping the South reduce poverty, the current international free trade structure is actually aggravating it. Already in a weakened position, the South is now deprived of many of the economic policies it needs to tackle them.
