Ukrainian President Volodymyr Zelenskyy on Monday pleaded with Western leaders to further isolate the Kremlin by closing their borders to Russian travelers as the war approaches the six-month mark.

The most important sanctions are to close the borders because the Russians are taking away someone elses land, Zelenskyy told The Washington Post .

He added that Russian citizens should live in their own world until they change their philosophy, noting the whole country should face consequences for Russian President Vladimir Putins invasion of Ukraine.

Theyll understand then, he continued.

Zelenskyy told the Post restricting Russian travelers for a year coupled with a ban on Russian energy would be a stronger deterrent to Putins continuing war, calling current sanctions weak.

While Europe and the U.S. have already closed their airspace to Russia, they have not prohibited Russian citizens from entering their countries.

Some European countries are already heeding Ukraines calls for tighter restrictions.
