Hugged by long, dry grass and weary acacia thorn trees, the banks of the Mungezi River in southeastern Zimbabwe’s arid Bikita district appear to be an unlikely site for the geopolitical maneuverings of global superpowers.

Across the water, shimmering in the heat, stand imposing steel and concrete structures — the brand new plants built by Sinomine, one of the several Chinese companies that have invested in Zimbabwe’s nascent lithium mining industry. Soon, Sinomine will be exporting the lithium from its Bikita mines to massive battery manufacturing factories in China. This neglected rural district is now one more pawn in China’s gambit to control the world’s supplies of rare earth elements and minerals.

The Mungezi River forms the border between Bikita and the equally poor neighboring district of Gutu. On a Friday afternoon in July, Nelson Chamisa, the young, charismatic leader of Zimbabwe’s opposition, is on the campaign trail.

“Our minerals are being exploited,” Chamisa says to the crowd at a rally. “You are getting nothing. The only thing you are getting are cracks in your houses from the dynamite blasts. Our people are still jobless, they still remain poor.”
