In Belarus there is a "Presidential Reserve Fund". This first fund is allocated, each year, an arbitrary sum directly from the state budget. Then there is another equally surprising structure: "The Economic Aid Fund to the President". These two "funds" are fed largely by the state budget, arms sales, tourism, rental of real estate, lottery games etc ...
These two structures also derive profits from taxes during goods transit operations, import and export operations in particular to Russia or the resale of goods confiscated by the customs administration. It is also possible for a 10% commission to be transferred to these "Funds" in certain international transactions involving the state or its companies. On the other hand, each big boss in Belarus is "free" to contribute , with a small financial contribution, to the development of Lukashenko's structures.
These two funds could never be controlled since they are the exclusive property of Lukashenko.
This fortune would be preserved partly in cash and on the other hand placed abroad under aliases or relatives of Lukashenko.
