Polish farmers block border crossings and many roads across the country to protest competition from its neighbor. Polish Agriculture Minister Czeslaw Siekierski said “total” import bans may be necessary for new product groups.

Poland banned imports of Ukrainian grain under the previous nationalist government but maintained the ban after a new pro-EU coalition came to power in October. Poland has been among Ukraine's biggest supporters since Russia's aggression against that country, but friction over Warsaw's unilateral ban on grain imports has damaged relations.
