The prime ministers of three Eastern European countries – Poland, Slovenia, and the Czech Republic – are traveling to war-torn Kyiv by train on Tuesday to meet with Ukrainian President Volodymyr Zelensky. Their dramatic visit was kept secret until the last moment and comes at a time when Russian forces are shelling Ukraine’s capital.

The New York Times reports:

The aim of the visit is to express the European Union’s “unequivocal support for sovereignty and independence of Ukraine” and present a broad package of support, said Michal Dworczyk, the head of the Polish prime minister’s office. He declined to provide further details.

“This delegation is de facto representing the European Union,” said Mr. Dworczyk. He added that preparations for the trip had been coordinated with the bloc’s top officials and that the decision to arrange the visit had been made last week at a meeting of all European leaders in Versailles, France.

The three leaders – Prime Minister Mateusz Morawiecki of Poland, Prime Minister Petr Fiala of the Czech Republic, and Prime Minister Janez Jansa of Slovenia – will present “a broad package of support” from the European Union.

Poland, in particular, has played an outsized role in managing the massive outflow of refugees from Ukraine. The U.N. estimates that 1.7 million Ukrainians have crossed into Poland since the outset of the Russian invasion. Many continue further west, but some stay, relying on the kindness of volunteers.

Poland has also been Ukraine’s biggest advocate within NATO, calling for increased military assistance.

The Guardian adds:

The EU member states formally agreed on a fourth sanctions package on Tuesday morning, including an asset freeze and travel ban on the Chelsea football club owner, Roman Abramovich.

He is described in the EU’s legal text as “a Russian oligarch who has long and close ties to Vladimir Putin”.

“He has had privileged access to the president, and has maintained very good relations with him,” the text adds. “This connection with the Russian leader helped him to maintain his considerable wealth.
