Airframers Comac and Bombardier have set up a cooperation promotion committee.
The committee will be responsible for defining cooperation objectives and joint projects, supervising the implementation of projects and resolving issues that may arise, says Comac.
Comac and Bombardier are now in "phase two" of their collaboration on exploring commonalities between the C919 and CSeries aircraft.
Bombardier first announced an agreement in March 2011 to examine potential cooperation with China on its CSeries programme. The Canadian airframer is also acting as an advisor to Comac on the ARJ21 regional jet programme.
