A few interesting tidbits:
"Indeed, over the next 20 years, Boeing has forecast that air carriers worldwide will require 28,600 commercial aircraft with a value of $2.8 trillion. The Boeing forecast is generally viewed as the world’s best analysis of the global market for commercial airliners and cargo aircraft. And this forecast isn’t limited to jumbo-sized passenger jets: It includes short-range connector planes, regional jets, cargo planes and the jumbos."
"China, alone, will require 3,400 new airplanes worth about $340 billion over the next 20 years, Boeing projected in its recent market forecast. That works out to sales of about $17 billion annually over the next two decades. About 2,650 of those commercial airplanes will be actual airliners, Airbus projected in a forecast of its own. Up to now, Chinese airlines have been placing huge orders with Boeing and Airbus to modernize their air fleets and close the customer-service gap on their foreign competitors."
========================
Currently the world's jumbo jet market (civilian) is mostly cornered by Boeing and Airbus. Western aviation industry is willing to work with other countries in building lesser "regional jets" but would not welcome effective competition in their bread and butter business (Boeing 7x7, Airbus A3x0).
China needs to import engine technology, simply because the domestic industry isn't up to task yet. Look in PLAN ships, lots of European imported gas turbines there.
