Dissertation (MA International Relations)The objective of this study was to understand how the non-involvement of the nonstate actors in Tanzania may have adversely influenced the implementation of the Common Market. The basic issue of concern is that the implementation of the Common Market in Tanzania has ignored non-state actors who are key players on the grounds. In addressing this issue as well as achieving the objective, non-state actors and private sectors participation in the EA Common Market were analyzed by using purposive sampling, stratified sampling and theoretical sampling. The findings showed that Tanzania non state actors have a duty to enhance dialogue among themselves on participation in EAC Common Market activities and the benefits thereof. The EAC must be seen as an opportunity to handle some of the developmental concerns in the Region and Tanzania in particular. This dialogue will enhance an understanding of the importance of Common Market integration in tackling economic developmental concerns in the Country. These findings pointed to the fact that Tanzania should strive to understand the views of non-state actors as far as the integration effort as the Common Market is concerned. The study recommended three areas for policy intervention in order for Tanzania non-state actors to be involved and have full participation in the EA Common Market. These are Government recognition of the voice of non-state actors, strengthening of regulatory institutions, and effective implementation of various policies which are present.
