Istrati shared the leftist ideals of Rolland, and, as much as his mentor, placed his hopes in the Bolshevik vision. In 1927 he visited the Soviet Union on the anniversary of the October Revolution, accompanied by Christian Rakovsky during the first stage of the journey (Rakovsky was Soviet ambassador to Paris, and by then already falling out of favor with Joseph Stalin). He travelled through large sections of the European part, witnessing celebrations in Moscow and Kiev. He was joined in Moscow by his future close friend, Nikos Kazantzakis; while in the city, Panait Istrati met Victor Serge and expressed his wish to become a citizen of the Soviet Union. He and Kazantzakis wrote Stalin a congratulatory letter that remained unanswered.
