Zambian miners killed one of their Chinese managers and severely injured another by pushing a mine trolley at them during a pay riot at a mine on Sunday.
The miners were on strike against management delaying to begin a new minimum wage and keeping the workers' pay lower than other chinese managed mines, BBC said.
Zambia increased minimum wage in July to $350 a month for shop workers, but the mine's chinese owners have not yet implemented the increase, BBC said.
China has increased investment within Africa for its abundance of raw material like copper, which Zambia is rich in supply, but Chinese companies have been criticized for migrating their poor worker's rights to Africa, Reuters said.
