The government is facing “continuous battles” in trying to resolve a dispute with Chinese suppliers of locomotives, he told lawmakers in Cape Town on Friday. “We remain optimistic with regard to that matter.”
Gordhan planned to discuss a dispute between China’s state-owned CRRC Corp. and South Africa’s central bank and tax authority. Relations with the company were already strained because Transnet sought to cancel a deal to buy as many as 1,064 locomotives from the Chinese firm and two other suppliers. CRRC retaliated by withholding spare parts, forcing Transnet to withdraw more than 300 locomotives from service.
Transnet’s declining performance has been costly for miners including Thungela Resources Ltd., Glencore Plc and Sasol Ltd., which exported 50.4 million tons of coal through the Richards Bay Coal Terminal last year — the lowest volume in three decades. Recent disruptions to Transnet’s services on iron-ore and cargo lines have also occurred due to cable theft, hobbling the flow of goods and other commodities.
“The repeated, repeated problems of theft of copper” and other crimes “which we cannot get on top of as the state” is affecting the breadth of state companies, Gordhan said. The Department of Public Enterprises is also responsible for companies including power utility Eskom Holdings SOC Ltd.
