First of all, this sentence, "When it comes to real combat, Chinese weapons and technology are simply fails like Temu made toys," makes me think he's not reliable at all.
I also would not think that China would sell advanced radar to Venezuela. It's a foregone conclusion that since you need full interconnected systems in significant numbers under well-trained hands to really win against sophisticated enemy attack groups, whatever China sold to Venezuela would be overwhelmed and defeated. Since they would not be able to win or even put up much of a fight, why risk the exposure of these major systems to enemy forces? It only makes sense to sell them small arms so they can drag an invading US ground force into Guerilla warfare.
but the truth is china really sell radar to venezuela , in mass propagranda/information warfare : quantity > quality . the mass don't care about technical complicated reason why this weapon system fail , why that system not
they only care about which one come out on top
and the way china sell weapon to other countries then don't care anymore basically offer china's enemy easy way to defeat those weapon
because the buyer didn't get much help from china in term of training , technical complicated co-op , regular update etc to use those weapon system effectively
and by that they lose and fail > china's weapon take a big PR hit , every defense reason after that are no use because the dmg already done
meanwhile you can just look at pakistan , china support pakistan well in term of how to use chinese weapon good > they success big time , give china weapon / military tech / industry a biggest PR victory since the end of korean war . shock entire work , silent tons of china hater
and now you look at US/west . clearly you can see the west care about their military PR image alot . so whatever time they sell someone weapon they clearly do alot of support or work than china ...specially when they send weapon to some nation highly likely gonna fight west's enemy in future/near future (israel , ukraine , taiwan , japan , korea , australia , even philipines)
and if they unable to support then they put in alot of restriction for the country got western/US weapon :
like if you failed in combat : hide + censor any wreckage remain as fast as possible , as soon as possible , never let those speard widely on internet
if you not sure you can win or atleast do big dmg then don't use our weapon to fight them , keep those weapon safe behind
or never use store HE shell in our tank to avoid turret toss
or don't use out F-16 in direct air-combat with russia/india (ukraine/pakistan case)
china don't do anything like that and this is dog eat dog , might make right world . there are no heaven being above to judge both side fairly > the side who never miss any chance to fked up enemy in all term all kind of warfare alway win .
that why we have this kind of mess now not even long after pakistan chinese weapon victory , clearly US/west/allied know china weakness very well and they (+india) clearly aim to destroy that rare and only PR victory china have
