Human Rights Watch (HRW) issued a report on 20 February 2013 titled "Zambia: Safety Gaps Threaten Copper Miners." It is a follow up to a longer report issued in November 2011 that charged China Non-Ferrous Metal Mining Corporation with human rights abuses at its Zambian subsidiaries.
Writing for Pambazuka News on 7 March 2012, Barry Sautman, who teaches at Hong Kong University of Science and Technology, and Yan Hairong, who is at Hong Kong Polytechnic University, respond to the HRW report in a piece titled "A Response to Human Rights Watch's Update on Chinese Copper Mining in Zambia."
The follow up report concluded there has not been significant progress in resolving the mine safety problems. Click here for a translation of the HRW report in Chinese.
