One of the provisions in the 1987 Constitution that the business sectors want to change is foreign and land ownership; if you are a foreigner who wants to set up a business here, you need a local business partner, and you can only own 40% of the business, and no foreigner is allowed to own land.
Still way better than in South Africa, you should look up Broad-Based Black Economic Empowerment Act 53 of 2003
designed "to help" black people or rather to actually punish white people, managed to turn the entire country into a shithole!
Or the Preferential Procurement Policy Framework Act 5 of 2000, in which basically as you're a black-owned company, you can offer the government twice as expensive goods the government will buy from you rather than from a non conformant white lead company

As long as you have economic growth (wiki gives me over 5% over the last years) it's still good, the problems will arise once you hit 1-2% and your per capita GDP is still at the bottom, then one might start thinking about radically changing laws, and I think everyone is scared of changing that, thinking it will trigger a buyout from Chinese investors.
So, you want investors, or you want half of your land to be owned by foreigners? Cause they come in the same package!
When the policy makers of a country decide on various policies in the public interest, leaving aside personal interests, then the prosperity of that country can be desired. But currently, in different countries of the world, policy makers formulate various policies considering their personal interests, where the common people face economic destruction instead of enjoying benefits, whereas it was supposed to be that the policy decisions would work in the public interest of that country.
What a load of useless garbage!
