 On 4 March 2020, Gutzeit was voted in as Ukraine's Youth and Sport Minister. At the Tokyo Olympics held in 2021, Ukrainian athletes won 19 medals (up from 11 medals in the prior Olympics), though only one of them gold.

 Referring to the International Olympic Committee's decision to reinstate Russian athletes as neutrals, Gutzeit pointed out in March 2023 that "neither us nor them" are satisfied with the decision, with the Ukrainians ardently demanding a blanket ban, while the Russians claim the IOC criteria is humiliating, hypocritical, and russophobic.

 In 2023, Gutzeit, who had competed with Russian Olympic Committee president Stanislav Pozdnyakov when they were teammates from Ukraine and Russia on the post-Soviet Unified Team at the 1992 Olympics, said he had only contempt for Pozdnyakov. He blames Pozdnyakov for vocally supporting Russia's invasion of Ukraine. Gutzeit said: "I don’t want to talk to him. I don’t want to know him at all. He is my enemy, who supports this war, who considers it an honor for athletes to take part in the war against Ukrainians, to kill Ukrainians. Therefore, for today and forever, this person does not exist for me.”
 On 8 November 2023 Gutzeit requested his dismissal as minister, so he could focus more on the his at work in the National Olympic Committee of Ukraine.
