Russia has blocked Google News on charges of spreading unauthorized information about Russia's invasion of Ukraine.
The block comes just hours after Google announced it would not allow users around the world to monetize content that exploits, resists or condones war.
Google's new policy affects any website, app and channel that earns revenue from advertising managed by the search engine.
It's long been a policy prohibiting ads from appearing next to any content that "incites violence" and says the new policy clarifies and expands on that rule.
"We can confirm that we are taking additional steps to clarify, and in some cases expand, our monetization guidelines relating to the war in Ukraine," a Google spokesperson said.
Google took action against Russian state-funded media in late February and stopped all advertising for Russian users earlier this month.
The latest ban could cut funding to western media that back Russia, even if they have no clear financial ties to the country itself.
Hours after Google's new policy, Russia's Telecommunications and Internet Regulator Roskomnadzor announced it was blocking Google News entirely for internet users.
"Based on a request from the Russian prosecutor's office, Roskomnadzor has restricted access to the internet service news.google in the country," the agency said in a statement.
"The cited US internet news sources provide access to numerous publications and materials containing significant and unreliable public information about the course of special military operations in Ukraine." he continued.
Roskomnadzor continues to take action against the US internet giant as the war in Ukraine has progressed. A week after Russia first invaded, they blocked Facebook and Twitter in apparent retaliation for two companies removing Russian state media including RT and Sputnik from their platforms.
The official description lists 26 cases of discrimination against Russian media by Facebook since October 2020. Initially, the ban only focused on Facebook itself, which has low penetration in Russia, so the popular apps Instagram and WhatsApp were not banned.
However, on March 11, they were added to Russia's blocked list following a policy change from Facebook to allow Ukrainian users to make violent threats against Russian soldiers.
"This is a temporary measure designed to safeguard the voices and expressions of those facing the invasion," Facebook said at the time.
