Oil giant BP has warned that further international sanctions on Russia could harm the company's profits.
The UK business owns a 19.75% stake in Russian oil firm Rosneft, which is the subject of sanctions preventing it from using US financial institutions for new loans over a period longer than 90 days.
In its second-quarter results, BP said further international sanctions on Rosneft or on Russia could have a "material adverse impact" on its investment in Rosneft, its business in Russia and its own financial position.
Profits for the quarter to June 30 were $3.18 billion (£1.87 billion), up by a third on the same period a year earlier but down 8% on the previous quarter.
The investment in Rosneft, which is Russia's biggest oil producer, was a factor in the improved performance by BP as profits from the relationship nearly doubled to just over $1 billion (£589 million) in the second quarter.
