For decades, the two countries have maintained strong political and economic ties, and China has funded multibillion-dollar Zambian infrastructure projects ranging from airports and railways to dams.
But the lawsuit filed by 176 Zambians against Sino-Metals Leach Zambia and NFC Africa Mining – two local subsidiaries of state-owned Chinese firms – alleges that a tailings dam wall collapse in February released acidic waste into streams, rivers and farms near the town of Kitwe, about 285km (180 miles) north of the capital Lusaka.
The farmers, who have termed the event an “ecological catastrophe”, claim the spill violated their constitutional rights and destroyed their livelihoods by contaminating their crops and livestock as well as creating health problems for local residents.
The petitioners further claim they were not immediately warned of the danger, forcing them to live in a contaminated environment for seven months.
