Deputy Prime Minister for Restoration of Ukraine - Minister for Communities, Territories and Infrastructure Development of Ukraine Oleksandr Kubrakov replied:
"@AKamyshin will lead the Office of European Integration of @Ukrzaliznytsia. This is our joint decision. Grateful to him & the entire team for their dedicated work. A year of resistance to the #RussianAggression showed the true indomitability of the railway family."
Kamyshin recently said that Ukrzaliznytsya could set up its own freight company in Europe by the end of this year. However, there are problems, including the low "speed of approvals in Europe".
Kamyshin began his career as an auditor with KPMG in 2006. He then spent several years working with private equity and other investment funds. In August 2021, he became Acting Chairman of the Board of Ukrainian Railways, and from March 2022, he was regular Chairman.
