It is absolutely weak in the sense that modernization has not been completed and still has a long way to go. We shouldn't let pride get in the way of objective analysis.I wouldn’t call it weak, simply untested in the current setting. I mean Ukraine was considered to be the strongest army trained by the west in Europe and Russia as a gas station in the middle of nowhere and right now the USA is trying everything from nuclear threats, blowing up pipelines of Allie’s and begging for weapons around the world because they far from being a strong military, is in fact a weak military propped up by the dollar and the fact they have nukes and even now their economy is in such a state that they sent Yellen to China to try and get them to save them like it is 2008. I believe in due time China will iron out its differences but really I believe that China is already very powerful (heck powerful enough to blow the USA back to hell if they get first strike and with Russia willing to help out because of basically everything the USA has done to them now, they have a very good chance of success there) but merely prefers to win a fight with an extreme advantage rather then start a fight now when it isn’t even required, especially with the USA looking to be in more of mess in a mere few weeks
Frankly, I would say that in many aspects China is severely lacking in what you would expect from the largest economy in the world by PPP. I'll grant that buildup and modernization started relatively recently in historical terms, but for the longest time the military was simply not taken very seriously in comparison to economic growth. That was a mistake the Song dynasty made and it cost them.
