An interesting news item from Tanzania. The Tanzanian government plans to include a clause in its new mining law allowing it to own shares in firms extracting what it considers strategic minerals. The mining sector is Tanzania's second largest foreign exchange earner after tourism, having earned $1.08 billion in 2008. The new law will also compel mining firms to buy goods and services locally when they are available. Critics have long complained that benefits from the lucrative sector were not benefiting the common citizen. The law currently allows the government to hold no less than 25 percent in companies mining gemstones like diamond, tanzanite and rubies, but is silent on other minerals. In the new law, the government will have the authority to take shareholding even if it is 10 or 15 percent in minerals that the government deems strategic.
