"as a result of Australian government sanctions, Rio Tinto has assumed 100 per cent capacity and management of QAL Limited until further notice."

QAL management asked Rio Tinto to step in and take full control of the asset after receiving legal advice that the operating structure did not comply with Australian sanctions, according to people familiar with the matter. After the sanctions are lifted, control will be restored to the previous joint venture structure, the person said.

Rio Tinto said it would follow all instructions from the Australian government and reiterated that it was ending business relations with Russian companies, which in fact made it difficult to achieve that goal because of its shareholding relationship.
