Abstract
This Project was developed from 2002 to 2005 in Central American countries and Andean Community, MERCOSUR and Chile. The main objective is to promote the commercial Exchange of medicines among South - South countries. The Natural Products were taken into account in the project from 2003. The small and medium enterprises were educated for the improvement of their activities in the chain value by virtual discussions and conferences during the main event. By means of this event the International Trade Centre (ITC UNCTAD/WTO) provided opportunities to the small and medium pharmaceutical and natural products enterprises to participate in Buyer/Seller meetings every year in order to promote their development.
