Thanks for the response naraic (and the others of course). Did these kind of political-economic sanctions also happen with industrialized European countries?
Probably but I think threats of sanctions is mostly hot air. The real threat would be reducing the reputation within one country leading to less trade.
The Espana's were the result in trilateral talks between Spain France and the UK after the Moroccan crisis. They were Spanish built by British owned firms. France required diplomatic promises that Spain would join a war between France and Italy on the French side iirc.
There was also trilateral Anglo German Portugese talks about theoretical Portugese battleships. I think they were going to be British built but Germany were to be bought off by have Portugal take loans from German banks.
The Germans felt that the Portugese wouldn't be able to pay the loans and intended to seize Portugese colonies as collateral when Portugal would default.
Wouldn't choosing between the UK and Germany also mean siding politically with that country? It certainly gave that country an advantage in war, as the example of the Turkish battleships in Englands shows.
Yes it would to extent but that can be mitigated against.
That is why there was often compensatory agreements and multilateral talks. If someone got something someone else would get something else.
Salamis for example was to be German built but component parts came from multiple countries.
Of a country might buy battleships from country but destroyers from another as happened in one of the South American naval purchases.
Edit:I do want to read up on the ordering process of the Norwegian coastal defence battleships as I don't know any of those details.
2nd edit: I believe that Germany expelling the Argentine naval attache as mentioned abovd was more to do with details of the German bid being allegedly leaked to other bidders than losing the contract.
