Ukrainian and Polish officials met in Warsaw on on Dec. 1 to work on a solution to end a protest by Polish truckers who want the EU to restate entry permits.

Protests by truckers over what they see as unfair competition from their Ukrainian peers started on Nov. 6, with four border crossings now under blockade.

As Polish protests blocking three major Poland-Ukraine border crossings stretch into their third week, negotiations have all but failed as Ukraine accuses the protestors of causing further harm to its wartime economy and the risk grows the protests could spread to other EU countries.

The queue of trucks starts more than 20 kilometres from Poland's eastern border. Hundreds of Ukrainian lorries are parked along the road in an unbroken line, caught up in a trade dispute that's putting new strain on Polish-Ukrainian relations.

Polish truckers have been blocking several crossings with Ukraine since Nov. 6 to demand tougher conditions for Ukrainian peers. Polish and Slovak truckers complain Ukrainian truckers offer cheaper prices for their services and also transport goods within the European Union,

Ukraine's top truckers union said on Friday its hopes of a rapid end to Polish trucker protests at the border were fading, as Kyiv prepared to evacuate its hauliers stranded in Poland.

Truckers in Slovakia joined Polish counterparts in staging a blockade at the border with Ukraine, escalating a protest over competition that Kyiv says has disrupted crucial humanitarian aid imports.

Ukraine on Friday said that the fallout from a weeks-long protest by Polish truckers on their countries' shared border was "catastrophic", as Slovak hauliers also began blockading crossings with their war-torn neighbour.
