Kyiv warned of serious economic consequences as Polish truckers and farmers along the border continued to block Ukrainian cargo from entering the EU nation, with intensified protests expected on February 20. “Blocking transport on the Polish border will have serious social and political consequences for both countries,” Oleksandr Kubrakov, Ukraine’s interior minister, posted on Facebook. Officials said Kubrakov held urgent talks with Jacek Siewiera, head of Poland’s National Security Bureau, regarding the blocking of traffic, particularly passenger transport. Tomasz Obszanski, head of the Polish Farmers Solidarity union, told RFE/RL that protesters’ demands center on calls to restrict imports of Ukrainian agricultural products entering Poland.
