In soviet times Sergei Teterin succeeded in junior tennis. He was a multiple winner of championships of Belarus, USSR and a European champion. At the dawn of Belarus independence he became the Belarus men’s team captain for the Davis Cup.
It is believed that none other than Tiateryn raised interest in tennis in Lukashenka in the nineties. Right after he became Lukashenka’s personal coach, the sportsman easily climbed the career ladder. In 1997 he became the first Deputy Minister for Sports and Tourism. Between 1999 and 2011 he was Assistant to the President for Physical Education, Sports and Tourism development Affairs. Later he worked for the Belarus Tennis Association, then ran the sports complex in Raubichi, then was the head of the Palace of Tennis.
In 2012 Sergei Teterin, Ihar Zaichkau and Aleh Kachan were dismissed from their positions of the Vice President of National Olympic Committee, Assistant for Sports and the Minister for Sports and Tourism respectively by Lukashenka. This was Lukashenka’s reaction to Belarus' failure performance during the Olympic Games in London. Moreover, Kachan, who worked as a Minister for 3 years, allegedly was facing criminal liability for building toilet facilities at his dacha at the cost of budgetary funds. However, a year later all three mentioned above came out in Tiateryn’s business.
In 2012 he made about $20.000. Previously, having had $18.5 annually in the National Olympic Committee, he had his house built in Drozdy in just 2 years, which approximately cost more than $350.000. It’s not clear, however, how much exactly he needed to start his new business, but connections might have come in handy.
According to the documents leaked by Cyber Partisans, Sergei Teterin, as a rule, acted in the following way - he wrote to Lukashenka to get his approval. The scheme worked because in the early 2010s they spent a lot of time together in informal settings. They were seen together collecting watermelons, cutting the grass and visiting beauty contests.
Tiateryn started with supplying imported food to a supermarket chain “Belkoopsoyuz”. In February 2012 Lukashenka severely criticised government operator’s work and ordered the establishment of bulk purchasing of critical imports in order to start competing with other distribution networks.
It was obvious that Tiateryn’s companies “BelGlobalStart” and “BelGlobalGarant” acted as mediators in supplying “Belkoopsoyuz” with tea, coffee, confectionery, grocery, fruits and frozen fish.
But in 2015 Tiateryn complaint to Lukashenka about “Belkoopsoyuz”. The substance of his letter was, roughly speaking, that his production was not being sold in all rural stores and the operator never paid for tea and coffee on time.
It must be said that Tiateryn didn’t have a good press in “Belkoopsoyuz”. And that is quite understandable. In 2016 “Belkoopsoyuz” was made to order furs processing from Tiateryn’s company “BelGlobalService” in Maladzyechna. Three years after The State Control Committee incriminated Lukashenka’s personal coach in overpricing fur processing services.
“Thus, the enterprise at the expense of “forced” fur processing in LLC “BelGlobalService” from 2016 to 2018 lost an estimated €350.000 in potential income” says the letter from The State Control Committee in Grodno region dated 16 January 2019.
