Author here. Indeed, Embraer and Bombardier are in the same
market as Comac for the time being, and I probably should have
mentioned the former if just because it's a pretty big player, but
Comac's ambitions are tied more closely to China's economic
success than Embraer's to Brazil's. Embraer is an old company
with a longstanding interest in smaller planes--their largest jet
right now has a passenger capacity of about 120.
Comac has been relatively frank about plans to expand beyond
commuter jets and larger single-aisle, limited range planes. In a
few years we'll probably be reading about Comac's 787
competitor. Embraer's focus, at least recently, has continued to
be on RJs and private jets. Anything's possible, though.
