The suspects, who are linked to two aluminum smelting companies located in Shai Hills, were apprehended on Thursday during an intelligence-led operation.
Cables, believed to be part of the missing consignment, were traced to an aluminum smelter owned by the Chinese, situated opposite the Shai Hills Game Reserve.
These cables were reportedly being melted into aluminum bars for export.
Operatives of National Security are also on a manhunt for another Chinese national who is currently on the run.
