Money talks 
If your skint, you buy what you can afford.
If our goods are cheep enough them people will buy them 
Yes, in business it is not who you like, but what is on offer, at what price, when, and what quality. The "old boys" clubs of imperialism are defunct now, and business requires what it needs every time.
Only nationalised companies may come under pressure to buy from certain quarters, but how many of those companies now survive? ??[/highlight]?
This might apply in Britain. As I said previously, sadly the Brits have lost their sense of pride when it comes to buying British first as opposed to foreign. Brits always buy on price and they care very little about where it comes from.
People still buy from people. Why do folk travel to meetings when most meetings could be done using high tech conferencing and so on. It is to press the flesh, have a few drinks together in the bar. Then they will "buy" from you.
Spain used to have a "pound shop" (100 pesetas actually) in every town. These were run efficiently by Morrocans. They are being run out of business by the Chinese. Not many Spaniards shop in them. It is mainly expats. The Spaniards prefer to buy from their own and pay a bit more. My neighbour says he will
nevergo in one as long as he lives. That is one reason why I say that we may just got a shock at the backlash IF we badly manage any Brexit from the EU.
The other thing to do is look at what cars folk drive in different EU countries. The likes of Spain, France and Germany stick mostly with their own made cars.
Maybe a lot of big contracts go out to tender but it isn't unknown for tenders to be so written as to exclude a company or a country. Again that is a
person choosing to do that.
