There is a certainly an element of being "untrustworthy" here but I would say that Russia's behaviour itself has driven this. Russia's invasion on Ukraine is ringing big red alarm bells for all of Central Asia for both of their elites
and their populations
Second element is that the Russian model is a failed one. I sometimes go and check their newspapers in their local languages and you will see 2 things there.
Either praise for the Western model (this has went down a lot recently) or praise for the Chinese model (gaining ground quickly). Nobody there seriously believes that the Russian model can and should be the blueprint for the future of their country.
As such I don't blame CA when they move away from Russia. China is far far more preferable as a partner to CA than Russia for the following reasons:
- China doesn't meddle in their internal affairs (which Russia does in CA)
- China can offer more economic benefits to these countries and their people.
- China can credibly offer an alternative (and quite compelling) model of development to the region that Russia simply can't do because its model is a failure.
- China doesn't have the reputation of habitually using its military to invade other countries. Contrast that with Russia, and you see why the overwhelming majority of their elites are terrified of Russia and thus are quickly moving towards China nowadays
And why does trust or not trust here matters? Countries are all about interests. Why does China and Africa cooperate. China and Middle East, China and Vietnam (lol). As long as interests are enough you can do a lot of things. If you see that you lost strength and thus countries turn away from you, you have no-one to blame than yourself for being weak
So yeah, for Russia's weakening in CA its due to their own fault. Their weak economy, weak diplomacy, weak R&D, weak (for a "superpower") military, weak industries, weak and incompetent national leaders etc.
China ain't doing any 5D moves. It simply focuses on itself, gets stronger, and naturally more "allies" are coming to hug its thigh
