LE BOURGET, June 15. /TASS/. Russia’s Irkut Corporation is fully satisfied with cooperation with European partners on the project of constructing MS-21 jet airliner, the corporation’s president Oleg Demchenko told journalists on Monday.

"I am very content with how we are working," Demchenko said, noting that "we have been working together for many years, and we still haven’t parted ways."

"Cooperation is observed" in the framework of the project, he added. "Regardless of politics, business is business, and it is observed," the corporation’s president stressed.

The Irkut MS-21 is a series of twin-engine short-range and mid-range Russian jet airliners set to replace Soviet Tu-134 and Tu-154 aircraft and its Western analogues. The first MS-21 plane is planned to take off in 2016. Serial production of airliners is to start after 2020.
