Hey! Here's a late response.
According the Geoffrey Roberts there were indeed some discussions of political rapprochement between Germany and the Soviet Union in early 1937, but they were far more minor than what the story you posted describes. David Kandelaki, Soviet Trade Representative to Germany, reported that Hjalmar Schacht, German Minister of Economics, was interested in discussing political issues of an indeterminate nature. The Soviets were interested and carried out further probes, but In February Hitler rejected any further discussions and on March 21 Schacht informed the Soviets that no opening was possible. Kandelaki and his associates were subsequently executed in the Great Purge, and the Soviets avoided political outreach with Germany until the spring of 1939.
