The president of Belarus Alexander Lukashenko will travel to Moscow tomorrow Wednesday for two days of talks with the Russian president Vladimir Putinas announced by the Kremlin.

Kremlin spokesman Dmitry Peskov said last week that the two leaders would discuss Lukashenko’s call for an immediate ceasefire in Ukraine in an upcoming face-to-face meeting.

Putin and Lukashenko will hold talks on “current bilateral and international issues” on April 5, ahead of the meeting of the Supreme Council of the Union State on April 6, the Kremlin said in a statement released today.

Russia and Belarus are officially part of the Union State, a borderless union and alliance between the two former Soviet countries, although long-standing plans for closer integration of their economies have been delayed.

Moscow is a crucial political and economic backer of Belarus, and Lukashenko allowed Putin to use Belarusian territory for Russia’s invasion of Ukraine last year.

Last month, Putin said Russia would deploy nuclear weapons “regularly” in Belarus.

Defense Minister Sergei Shoigu said today that Russia is boosting Belarus’ nuclear capability in response to Finland joining the NATO military alliance.
