The United States has discovered nearly $1 trillion in untapped mineral deposits in Afghanistan, far beyond any previously known reserves. The previously unknown deposits including huge veins of iron, copper, cobalt, gold and critical industrial metals like lithium " are so big and include so many minerals that are essential to modern industry that Afghanistan could eventually be transformed into one of the most important mining centers in the world. American and Afghan officials agreed to discuss the mineral discoveries at a difficult moment in the war in Afghanistan. Just last year, Afghanistan's minister of mines was accused by American officials of accepting a $30 million bribe to award China the rights to develop its copper mine. The minister has since been replaced. American officials fear resource-hungry China will try to dominate the development of Afghanistan's mineral wealth, which could upset the United States, given its heavy investment in the region. After winning the bid for its Aynak copper mine in Logar Province, China clearly wants more, American officials said.
