developmental terms

No, I am not at all calling China's capabilities low in terms of creating a war machine.

I am talking in terms of how quality of life has been affected by either of them in places which both countries are calling as their own (see my points in the above comment). While China tries to call Arunachal Pradesh and parts of J&K and its people as under itself, India is what sends the disaster relief resources, whereas China considers blocking natural resources to try and increase discontent of the people living in those areas.

China took longer than India to even admit the increasing air-quality problems in high pollution states,^[although for both countries, the actual metrics being used to report them hardly align with actual types of pollutants and the mitigations in response have been "too little too late" for both] which shows me that the govt. doesn't like admitting facts. And personally, I am fine working with people who fail a lot, as long as they are consistent in communication and don't try mixing lies into reports. Because trustability is an important part of any relationship, which also applies to governments.^[The main reasons I give flak to US govt and organisations is due to their lack of consistency, which makes them very less trustworthy.]

And I am not even going to point out the actual quality of buildings that you might have been a part of your metrics, simply because I expect enough people to have pointed those (and other similar conditions out to you).
While Indian buildings aren't particularly great either, I am in a 10+ year old building which was not designed for earthquakes and has still not cracked (much less collapsed into a death trap) despite multiple of those.

Then comes the destruction of values over the years. China has had a rich culture of thousands of years and any such civilisation develops values and traditions that are conductive to longevity.
But the recent values shown by adults (not even children) from China has indicated an erosion of older values that were developed over the centuries in China. This is not something that happens easily without intervention from higher powers (and I am inclined to think it was the govt, unless you know of any other power that might have to gain from activities that cause this side-effect).
While there has been quite a lot of food adulteration problems in India, there are some lines that people would not cross. Specially the working class (who actually care about values unlike the business class) would never. But the normal people that seem to come out of China to set examples, don't seem to be doing any good for its reputation.
