Battles of Khalkhin Gol
In 1937, Tōgō was appointed as Japanese ambassador to Germany, serving in Berlin for a year. After Tōgō was replaced as ambassador to Germany by Hiroshi Ōshima, he was reassigned to Moscow as the ambassador to the Soviet Union 1938–1940. During this time, he negotiated a peace settlement following the Battles of Khalkhin Gol between Japan and the Soviet Union, and successfully concluded the Soviet–Japanese Neutrality Pact in April 1941. He was then recalled to Japan by then Foreign Minister Yōsuke Matsuoka for reassignment.
