With the stroke of a pen, Russian President Vladimir Putin formally enacted a series of anti-LGBTQ+ amendments banning marriage equality and transgender adoptions, and centering “a belief in God” as a core value of the country. The homophobic and transphobic amendments were passed last July in a national referendum, with over 77 percent of voters casting their ballots in support of the measures. According to a report in the AP, the new rules also reset Putin’s term limits as president, meaning he can serve an additional two six-year terms in office.
Yeah it's still imperialism to carry out territorial expansion for more resource extraction, but Russia isn't really doing that. Like, what can you even list that they're doing? They support Assad in Syria (the war has basically been won and most people just want the war to end and probably don't want an American-backed leader), and annexed the part of Ukraine that from what I understand basically wanted to be part of Russia, and the rest of Ukraine got coup'd by the US previously and became extremely anti-Russia with NATO stuff of course. Whatever else they're doing is probably run of the mill capitalist stuff which you could chalk up to imperialism maybe (?) but isn't remotely on the same scale as western governments.
In a lot of cases, Russia wants more influence in eastern Europe, which could include having governments that favor them and economic policies that benefit them.
Now, I am not saying that they are the only government that has, is doing or will do this, but I would consider it imperialistic, they are just not a power at the same level as the United States, China or even the European Union.
