In the first weeks of the war, the border of Belarus-Ukraine formed a big traffic jam. The Belarusian side refused to release drivers. But the Furs had nowhere to go, as the Russian army used the territory of Belarus to attack Ukraine. Russia’s attack on the northern part of the country (Kyiv, Chernihiv, part of the Sumy region) made Ukrainians hostages of a foreign country and their trucks.
The Ukrainian side immediately reacted to the situation. However, the state security committee of Belarus did not want to do anything. They installed additional air defense systems on the border with Ukraine. This made the process of returning Ukrainians home even more difficult.
The return of the truckers was handled by the ambassadors of the 2 countries. After a series of negotiations, the countries had to return truckers: Ukraine — Russian, Belarus — Ukrainian, Ukraine — Belarusian. Note that Poland also participated in the negotiations. But when the Ukrainian side released Russian truckers to return home, Belarus broke the treaty. Ukrainian drivers were not released to Ukraine. They said that the Ukrainians would return home after all Belarusians had returned to their territory.
Now all truckers are in their countries. However, the state security committee of Belarus states that this operation was carried out only by them and does not violate any treaties.
