Iran oil sanctions could advance China's 'petro-yuan' - Reuters News

Pricing imports in Yuan will spare China the cost of exchanging dollars and would go a long way in helping the world's second-largest economy internationalize its currency - something that is widely seen hurting USD's international clout.
