The future is looking sparkling, page-29

JawDropper you are wrong and this is why in my opinion.
By holding a smaller percentage of any oil gas or mining operation the Angolan government will increase international investment in the country that will inturn increase the amount of payed workers and the tax they pay and tax the companies pay along with more cash flow being spent in the country.
The government would make more money on tax rather than try and hold on to a larger share of each project.
Western countries have learned that a system of tax is better than holding onto assests and I believe the Angolan government is following in our footsteps.
