The joint venture is 50:50 between the two countries and Russians will build a new engine named PD-35 for the plane.
According to UEC, the engine can rival U.S. and British models of the next generation.
This is a long project that's not going to finish in a few years. "The first flight of the aircraft is scheduled for 2025-28," Viktor Kladov, Rostec's director for international cooperation and regional policy, told China Daily.
According to data collected by U.S. aerospace magazine "Aviation Week & Space Technology", the CR929 will be larger than Airbus A330 and requires larger engine thrust to push it up.
It also reported the length and wingspan of the plane will be more than 63 meters.
Three types of CR929 will be produced, with capacity ranging from 250 to 440 people.
With all that said, the plane was still in its design phase as of late 2018. Each of the specifications is subject to change.
