Will Poland benefit from border blockade? What and Who Can Stop the Escalation of the Conflict on the Polish Border?

According to various sources, the attackers damaged up to 180 tons of agricultural products. The grain was scattered at the Kotomierz station, near Bydgoszcz, quite far from the Ukrainian border.

Ukrainian grain was poured out of 8 sealed gondola cars. Customs cables with a thickness of 8 mm were cut. In this way, the double side doors were opened.  The grain did not threaten the Polish economy in any way, because the cargo was in transit to the port of Gdansk, from where it was sent to Morocco.

Polish protesters are destroying Ukrainian grain for the fourth time.

"Wagons with corn from Ukraine broke down near Bydgoszcz. An error in the automatic closing system of the dampers," a member of the pro-Russian Confederation party accompanied a video of spilled grain on social media with such a mocking post.

And at the Rava-Ruska-Hrebenne checkpoint, Polish farmers scattered nails and screws all along the road so that Ukrainian drivers, who are already standing in line, puncture their wheels and could not continue driving.  It is obvious that the situation with the border blockade has reached its peak point and has very negative consequences for cooperation between the two countries.

What and who can stop the escalation of the conflict? Is there a way out of this situation? What steps does Ukraine plan to take in response?
