no doubt any country like to support their domestic industries, would not say that Russia was alone in that area.
large contracts with aerospace companies typically require some domestic contracting as part of the import order, i.e. when Canada buys a large number of jets from an American company, the company is typically required to spend or procure a contracted minimum amount from Canadian industry. Sometimes they will set up a subsidiary in country and buy from that subsidiary. This is known as an offset and typical of these large contracts. Bombardier for this order have indicated they will set up a turboprop assembly line in Russia. (not a case of jobs leaving the country)
loans of this nature virtually always come with a sovereign guarantee so not much chance of a default. Russian's have not defaulted on other historical orders with Bombardier.
the newer jets which are in favor these days are about fuel economy for a specific size and range aircraft. the airlines to remain competitive require these economies to stay in business. the industry manufacturers have targeted segments of the market to specialize in so as not to go toe to toe with each other with lower prices, rather they service the niche they specialize in.
not sure why an airline who is in business to make money would prefer a substandard domestic product to a superior foreign product unless tariffs forced the economics, rather they would buy the best tools for the job, national pride aside. its called free enterprise
have a little faith in Canadian industry, they are competent and navigating the international customer base with a good balance of competence, competitiveness, and risk mitigation. Bombardier rapid transit trains have been selling internationally quite well in the past 10 years.
doubt if commercial lenders, EDC included would loan without a sovereign guarantee for an order of this magnitute to a country like Russia so all in all I am not sure why the assumption of default unless you are just Russian bashing......
