Speaking in an interview on Belarusian state television on 27 January, Lukashenka said the creation of a unified state would be "time- and effort-consuming."
The Belarusian president said that there are also unresolved issues to be considered, for example the approval of a single constitution and a shared currency.
Belarus and Russia have been speaking about a union since the mid-1990s, but integration efforts have often stagnated.
