Rio Tinto/Chinalco

Tom Albanese, chief executive of Anglo-Australian miner Rio Tinto, has warned of "resource nationalism". A proposal for Chinalco, one of China's biggest state-owned mining groups to take a $19.5bn stake in Rio Tinto, collapsed last year. This dealt a blow to China's global corporate ambitions and its efforts to gain clout in the natural resources market. Soon after, four Rio Tinto executives were arrested in China on bribery charges.
