Polish PM Tusk arrived in Ukraine yesterday for his first visit to Ukraine since his pro-European government took power last month. Tusk will seek to reset relations between the two neighbors after the previous law and justice government imposed a unilateral ban on grain imports that quickly escalated into a political standoff. Poland’s new premier, a former European Council president, has promised to rally flagging support for Kyiv among Western allies. However, he also pledged to be more assertive in relations with Ukraine and has so far not committed to lifting the grain ban.
