Just back from Moz and mostly saw the other side of the coine i.e. that the locals are benefitting greatly from all this 'foreign' investment.
Mozambique now has excellent investment laws according to which most, if not all of these exploitative and dodgy deals are illegal. Lacks the will and/or the capacity to implenent the laws. Investors are not boyscouts and will exploit anyone if given the opportunity - mind you so will the missionaries, industrialists, NGO's, philanthropists, journalists etc.
