Belarusian President Aleksandr Lukashenko stated that the other post-Soviet countries need to get closer to the Union State of Russia and Belarus.

"Today, the countries of the post-Soviet area should be sincerely interested in rapprochement with the Union State if, of course, they want to preserve their sovereignty and independence. We are convinced that only together is it possible to counter global challenges," Lukashenko said in a video message shown at the plenary session of the forum of the regions of Belarus and Russia.

According to him, "those who still have doubts should realize: without quick unity and solidarity, strengthening of interstate ties and just normal human relations, we may not exist tomorrow."

"At this phase, our [Russia and Belarus] union plays the role of a locomotive in the general flow of integration processes. It is an example, a model of interstate cultural and economic cooperation," said the President of Belarus.

To note, Armenia also is a post-Soviet country.
