“Similar trips will be organized in the opposite direction,” the Ukrainian railway company said. The state-owned company also released a video showing a train loaded with more than a dozen trucks.

Polish transport companies have been blocking several important border crossings with Ukraine since the beginning of November. Freight forwarders complain of “unfair competition” from Ukrainian companies after the EU suspended a series of border transport requirements because of Russia’s attack on Ukraine. Freight transport has therefore largely come to a standstill.

On Monday night, the Dolhobyczow-uhryniw crossing was opened to empty vehicles. The government in Kiev said this was a first step towards resolving the conflict. At least two rounds of negotiations between Kiev, Warsaw and the truck drivers had previously failed. The EU Commission accuses the Polish government of not doing enough to find a solution.
