How many countries traded with Germany that they weren't technically allied with -- Sweden ? Almost everyone except Russia joined the Tripartite Pact. But Russia had the non-aggression pact, joined in carving up Poland, agreed to the spheres of influence, and by 1940 supplied Germany with 66% of all phosphorous imports, 63% of Chrome imports, 55% of magnanese imports, and 33% of oil imports. As far as I know, generally, other countries did trade with Germany but were more or less for one or two things and not as large of an individual share as this.

I get that the "alliance" was a matter of convenience for both and that both expected to fight and never joined by a treaty/pact. So, yeah, they weren't allies in the sense that Britain and the US were. My only point was the relationship was more than just the spheres of influence and the non-aggression treaty.
