Russia does the same to countries in their sphere of influence who even think about approaching the west. I'm looking at Georgia, Moldavia and now Ukraine. Also they really like to meddle in Africa and the middle east through PMCs like Wagner, prop up local dictatorships and harvest labor and natural resources for themselves.

China is also trying their hand at the imperialistic game, although they are newer at it. They are trying to enter many African countries and stationing there Private Security Companies (which are paramilitaries still controlled by the Chinese government, because of course they are). In Asia they are also trying to increase their influence. In the South China Sea they are trying to claim other nations exclusive economic zones as their own while in the Indian Ocean they are trying to secure military ports by forcing 99 years leases (similar to the British lease on the port of Hong Kong). I believe this plan is called the string of pearls and I also believe Indians consider it a way of encircling them (China-Pakistan corridor, China-Myanmar corridor and in the ocean ports in Cambodia, Sri Lanka, Pakistan, Djibouti and the Mauritius).

Let's say that all major powers have tried and keep trying their hand at imperialism. The only difference is that the US has a much bigger economic power than Russia and has been playing the game for a lot longer than modern China
