Chinese narrow-body aircraft manufacturers will break the market duopoly of Boeing and Airbus by grabbing at least 5 percent of the domestic market by 2020, according to an industry plan unveiled on Thursday.

Officials at the Ministry of Industry and Information Technology said the plan is the country's first national development outline for the civil aviation manufacturing industry.

The sector is expected to realize annual sales of 100 billion yuan ($16.16 billion) by 2020, according to the blueprint, and a growing number of aircraft being used on general aviation services will be built by domestic companies, it said.
