I don't get what you mean. This is about an APC/IFV tender for the Kazachstan military.
Sorry, I'm kind of bringing in some new ideas out of the blue.
I'm wondering if this if this is a precursor to upgrades for the UAE vehicles.
I'm thinking, they already did the integration work for the BMP-3 turret onto the chassis. The armament is generally the same, so why devote the time to integrate a whole new turret unless this was already something in the works? Plus nothing in your link would indicate that the existing BMP-3 turret wouldn't fit the bill.
The only issue of course would be the supply of Russian turrets would be an issue given the current war, but this doesn't seem like something slapped together in the past year.
Pure conjecture of course...
The only other explanation would be that Kazakhstan really wanted these Chinese systems, and were impressed by some kind of other demo, but how likely is that?
