The US has slapped sanctions on Vladimir Kiriyenko, CEO of Russia's dominant social media network, VK, barring him from doing business with any US entity.
As The Verge notes, VK, formerly VKontakte, has around 70 million active monthly users in Russia and is the dominant social media platform in the country.
Kiriyenko has been CEO since 2021. The platform was created in 2006 by Pavel Durov who wanted a homemade alternative to Facebook. In 2014, he was ousted from the company by a hostile takeover from an investment fund with ties to Putin.
