Plenipotentiary representative of the self-proclaimed Donetsk national Republic in the negotiations of the contact group on Ukraine Denis Pushilin expressed hope that the agreement on the withdrawal of weapons with a calibre of not more than 100 millimetres will be signed Thursday in Minsk. "The positive is that the subgroup on safety exhibits at least attempt to come to a common opinion. Unfortunately, in the most recent time the situation changed again with the Ukrainian side. Anyway, tomorrow will continue the meeting of the subgroup on safety. Hopes remain, albeit small, that (the issue) will be solved ", - said Pushilin.
