Sarawak Report has just released results of a probe into CMS’s dealings with Rio Tinto Alcan. The UK-Australia listed company obtained a license to construct a major smelter at Simalajau in 2007, using electricity from Bakun. According to Sarawak Report, the previously-announced joint venture between Rio Tinto and CMS is nothing of the sort, and the Taib family controls virtually the entire enterprise. If that’s true (and there is some documentary evidence to support the accusation) it may  be one reason why Rio Tinto has so far stalled on implementing the deal.
