Those tensions ended a long time back.

Russia and China have been working partners for some time now.

China's foreign policy is directed solely to helping the economic development of other countries.

Some in the US still do not understand that communism ended,
ans wish to continue to pretend that it is still going on, mainly to justify arms production in their states and districts arms plants.

I call it "the search for enemies". You need enemies to have a military, and you need the military to have arms sales.

US tolerance of Israel's theft of Palestinian land may be viewed in this light as well.

Russia is simply responding to forward US basing against a threat which simply does not exist, as they are not making it.
