Tanzania President orders wall built around tanzanite mines, says govt will start buying stones

Tanzania's President on Friday ordered the military to build walls around its tanzanite mines and directed the central bank to buy the precious stone to boost reserves – the latest twist in a spat with mining firms over alleged tax evasion. "All tanzanite gemstones will be controlled and will pass through one gate and he (President John Magufuli) ordered the (central) Bank of Tanzania to take part in the tanzanite buying trade," a statement from the presidency said.
