Russia's oil giant Rosneft is working with China's petroleum and chemical corporation Sinopec on the issue of mutual payments in national currencies, the head of the Russian company said Saturday.

"For the sale [of oil] in national currencies it is necessary to provide our traders with available financial resources. Customers will insist on a comprehensible exchange rate. We need to work more thoroughly here, clear all the details," Igor Sechin said in an interview with Rossiya-24 TV channel.
