Could Japan turn to the Soviet Union for more raw materials and manufactured goods?
Short answerOnly to a limited extent; existing trade already captured much of what was available, and Barbarossa sharply constrained further Soviet supply.
NotesJapan already received some raw materials and manufactured goods from the Soviet Union under its existing arrangements. There was little room to expand that supply after Operation Barbarossa. Soviet economic activity increasingly served the Soviet Union's own wartime requirements. Additional trade offered only limited relief for Japan.
