The blocking of the Polish-Ukrainian border, no matter what slogans it is accompanied by, has no justification, Spokesman of the Ministry of Foreign Affairs of Ukraine Oleh Nikolenko said.

"Land borders remain important in the context of Russian aggression. The actions of Polish protesters and individual radical Polish politicians undermine the Ukrainian economy and resistance to repelling Russian aggression. The border of Poland and Ukraine is also the border of the EU. It should not be hostage to any political interests," Nikolenko said on Facebook.

The Ukrainian Foreign Ministry also considers the aggressive attitude of protesters towards Ukrainians and Ukrainian cargo crossing the Polish-Ukrainian border unacceptable.

"Anti-Ukrainian slogans heard at the border confirm the politically motivated nature of the action. Its goal is to provoke a further aggravation of bilateral relations. At the same time, the protesters in no way mention the threats associated with the import of grain and other types of agricultural products from Russia and other countries," Nikolenko said.

The Ukrainian Foreign Ministry calls on the Polish authorities to provide a legal assessment of the actions of the protesters, ensure the unblocking of the border and take measures to stop anti-Ukrainian rhetoric, which is based on baseless arguments.

"In conditions of external testing, it is very important to maintain the level of solidarity that Ukraine and Poland have built in recent years. Ukrainians and Poles must defend good neighborly relations, repel any attempts to undermine mutual trust and jeopardize the security of our states," Nikolenko said.
