Ukrainian President Volodymyr Zelenskiy arrived in Slovakia on Friday to visit Slovak President Zuzana Caputova, according to his and her offices, as part of a tour of various NATO countries to rally support for Kyiv’s quest to join the military alliance.

Zelenskiy arrived in Slovakia after negotiations in the Czech Republic and Bulgaria the previous two days, and he is scheduled to travel to Turkey later on Friday.

“Slovakia is next,” Zelenskiy tweeted, adding that he would see Caputova, Prime Minister Ludovit Odour, and Parliament Speaker Boris Kollar.
