China and Russia have reached consensus on technologies to be used in the joint development of heavy-lift helicopters.

Chairman of the AVIC Helicopter Company, Yu Feng, says the two countries held the seventh round of negotiations to cooperate in developing heavy lift choppers.

The Aviation Industry Corporation of China signed a framework agreement with Russian Helicopters last May.

The project is going forward as planned.

Heavy helicopter refers to those with a take-off weight of over 20 tons.

The cooperation will fill a blank in China's helicopter industry.
