Polish Infrastructure Minister Andrzej Adamczyk has sent a letter to Ukrainian Deputy Prime Minister Oleksandr Kubrakov, in which he proposed Kyiv to meet the demands of protesting Polish truck drivers, Ukrainian media reported, citing the Polish Infrastructure Ministry's statement published on its website.

The electronic queue system was behind the protests, among other reasons, Adamczyk said.

"This has resulted in a substantial increase in the waiting time for vehicles registered in the European Union, which are returning from Ukraine without cargo, to cross the Ukrainian-European border," Adamczyk was quoted as saying in the statement.

Adamczyk urged the Ukrainian side to take urgent measures to meet the Polish truck drivers' demands, in particular, drop the requirement to register in the electronic queue of vehicles at the two border checkpoints Zosin-Ustyluh and Nizhankovychi-Malhowice.

In addition, the protesting truck drivers demand the reinstatement of international transportation permits for Ukrainian transport companies, which were canceled in accordance with the EU-Ukraine agreement (the so-called transport visa-free regime), the Polish Infrastructure Ministry said.

In this regard, Adamczyk asked European Commissioner for Transport Adina Valean to reinstate the validity of such permits. He also called on European Commission President Ursula von der Leyen to support his address to the Ukrainian government to abolish the electronic queue system.
