US made or US derivative infantry gear is widely used all over the world. I don't see very much PLA gear being used at all, except the occasional holosun optic. In the modern age, the PLA is perfectly capable of producing high quality, high end, high durability gear, AS WELL AS producing tons of it. For example, argus, ADNV, etc. As you've seen in the ukraine war, whilst drones, artillery, and high caliber weapons do most of the work, when it comes to infantry fighting, you still need well equipped infantry with superior capabilities to hold trenches, attack fortifications, and plug gaps in the line.
I would definitely argue that having higher quality infantry gear (Thermals, thermal fusion, NVGs) in particular is worth the tradeoff in weight. You don't see videos of soldiers escaping a hail of gunfire by doing rolls or fancy corner peeks, or any specific movement tricks.
The PLA is perfectly capable of fielding a large quantity of very well equipped infantry, it has the budget, the technological ability, and the manufacturing capability. And it can choose to do so whilst also developing the air force and navy. I just hope they realise soon enough that infantry capability is still important in the modern battlefield. Because there is definitely a lack of institutional knowledge, by far the most obvious for the ground force, which will take time to develop, unlike the issuing of high end gear to every grunt.
