The type of mutual commercial relations between Iran and Nazi Germany with the security of economic commercial benefits paved the way for an obligation in the continuity of this trend for the country. In spite of unwillingness in Farvardin of 1319, Iran made a contract with the Soviet Union on trade and sailing. Termination of this contract under the condition that Iran was unwilling in advance, arises this question that what were the effective factors in the termination of the contract on sailing and trade between Iran and the Soviet Union in 1319? This question in the article was surveyed according to historical research by using archive documents, journals and historical books.
