Genden has been described as "imprudent; shrewd; full of guile; quick tempered; loquacious; straightforward; belligerent and arrogant". He publicly criticized Stalin and the Soviet Union during moments of intoxication; for example he once openly called the Soviet Union "Red Imperialists". He became famous for fearlessly confronting Stalin during their public meetings in Moscow and was one of the few to stand up to Stalin's despotic character. In March 1936 Genden was removed from his offices of the prime minister and the foreign minister and placed under house arrest. Genden traveled to the USSR; ostensibly for medical treatment; in April 1936. In 1937 he was arrested and under interrogation admitted to conspiring with 'lamaist reactionaries and Japanese spies'. He was executed in Moscow on November 26; 1937.
