The way to stop Russia from annexing any more of Ukraine’s territory, President Volodymyr Zelensky said Monday, is for Western countries to announce that they would ban all Russian citizens in response.

In a wide-ranging interview with The Washington Post, Zelensky said that “the most important sanctions are to close the borders — because the Russians are taking away someone else’s land.” He said Russians should “live in their own world until they change their philosophy.”

Ukrainian President Volodymyr Zelensky is urging Western governments to bar Russians from entering their countries — declaring that they ought to “live in their own world until they change their philosophy.”

The leader of the besieged country made the request in an interview on Monday with the Washington Post as the Pentagon announced another $1 billion aid package to Ukraine.

Zelensky told the newspaper that “the most important sanctions are to close the borders — because the Russians are taking away someone else’s land.”

Ukraine’s president called on the West to impose a blanket travel ban on Russians, an idea that has found support among some European states but angered Moscow, which pressed on with a fierce military offensive in eastern Ukraine.

President Volodymyr Zelenskiy’s idea looked likely to divide the European Union, where differences on how to deal with Moscow have long persisted between some eastern and western members.
