RIA Novosti is a Russian state-owned domestic news agency, that belongs to Rossiya Segodnya, owned and operated by the Russian government.
On the 26-February, a little more than 48 hours after the start of the so-called "special military operation" by Putin's Russia, an article was published on the RIA Novosti website entitled "The new world order". This article was later taken down but it was up long enough for it to be saved under WebArchive. An English version of it was also shared around the same time in a Pakistani-based website named The Frontier Post and that page is still available.
The article gives an explanation for the invasion and in a way it gives the main reason behind it. It is very much aligned to Putin's speech from the 21-February, where he mentioned the need to correct the errors from the past in regards to Ukraine that, in his own words, was not a real country.
