This 122-page report details the persistent abuses in Chinese-run mines, including poor health and safety conditions, regular 12-hour and even 18-hour shifts involving arduous labor, and anti-union activities, all in violation of Zambia’s national laws or international labor standards. The four Chinese-run copper mining companies in Zambia are subsidiaries of China Non-Ferrous Metals Mining Corporation, a state-owned enterprise under the authority of China’s highest executive body. Copper mining is the lifeblood of the Zambian economy, contributing nearly 75 percent of the country’s exports and two-thirds of the central government revenue.
