DAR ES SALAAM, Sept 20 (Reuters) - Tanzanian President John Magufuli has ordered the military to build a wall around the country's tanzanite mines to counter smuggling, and said he had directed the central bank to start buying the precious stone to boost reserves.
"All tanzanite gemstones will be controlled and will pass through one gate and he (Magufuli) ordered the (central) Bank of Tanzania to take part in the tanzanite buying trade," said a statement from the presidency.
