Jumangarin has been appointed as the Minister of National Economy. He is known for his memorable phrase, "Don't annoy me!"

On December 21, the President of Kazakhstan, Kassym-Jomart Tokayev, signed a decree relieving Nurlan Baibazarov from his position as Minister of National Economy. The reasons for the resignation have not been disclosed.

55-year-old Zhumangarin, a native of the Aktobe region, studied in Russia and graduated from the Moscow Power Engineering Institute with a degree in "Thermophysics." Prior to entering public service in 2005, he worked in the oil industry.

In 2017, Zhumangarin became the Vice Minister of National Economy, and two years later, he took the position of a member of the board (minister) for competition and antimonopoly regulation at the Eurasian Economic Commission (a permanent supranational regulatory body of the Eurasian Economic Union, which includes Armenia, Belarus, Kazakhstan, Kyrgyzstan, and Russia). In 2020, Zhumangarin was appointed head of the Kazakh Agency for Protection and Development of Competition, and in 2022, he served as Deputy Prime Minister and Minister of Trade and Integration. In September 2023, he was relieved of his ministerial duties but remained in his role as Deputy Prime Minister.

Zhumangarin is remembered for his phrase "Жынымды келтірмеңізші!" ("Don't annoy me!"), directed at journalists. In February 2019, reporters asked Zhumangarin, who was then the Vice Minister of National Economy, about rising tariffs and received a blunt response.

“I talked about tariffs in parliament yesterday. The event was about small and medium-sized businesses. You came here to ask me about tariffs? Come to me officially. I will tell you everything about tariffs from A to Z. Жынымды келтірмеңізші!” — he said.

In August of this year, Vice Prime Minister Zhumangarin stated in an interview with Bloomberg that Kazakhstan would not "blindly follow" sanctions against Moscow, especially if they affect the interests of the republic and the companies operating there, which serve as major employers in their regions.

“We will not allow our own producers to be banned from trading,” — said Zhumangarin.

At the same time, he added that Kazakhstan would continue to adhere to the main restrictions, as the country "cannot withstand" direct sanctions.

The authorities of Kazakhstan have stated that they do not support Western sanctions against Russia but noted that they do not intend to allow the use of Kazakhstan's territory to circumvent these restrictions. Several companies registered in Kazakhstan are on the EU and US sanctions lists for their alleged involvement in the supply of sanctioned goods.
