Rosneft's board in April recommended a full-year 2017 dividend of 10.48 roubles per share, or 50 percent of its annual income.

Sechin said Rosneft was also considering opening its own network of petrol stations in Germany.

Rosneft supplies Germany with fuel via petrol stations operated by its partners BP and Total, he said.

"But it's entirely possible we'll also develop our own network," Sechin said.
