With it, it is suffice to say that indian airlines won't be getting those permissions.
Strictly speaking, I wouldn't fully endorse that statement of yours.
Airspace management in China has long been absolutely dominated by the PLAAF. Airspace resources available to civil aviation are under the PLAAF's strict control.
For a long time, the PLAAF has opened only about 20% of the airspace for civil aviation use. This has frequently led to congestion along flight paths and subsequent delays for Chinese civil flights.
Chinese civil aviation companies and regulatory bodies have repeatedly requested—during government meetings—that the PLAAF open up more airspace. The PLAAF’s response is invariably: "We will give it serious consideration..." "We are studying it..." or "We are planning for it..." Yet, actual progress has been exceptionally slow.
Currently, the airspace available to Chinese civil aviation has expanded to roughly 34%.
However, even within the airspace designated for civil aviation, emergency closures due to military exercises occur frequently. In China, it is very common for flights to be forced to detour, face delays, or enter holding patterns due to "airspace restrictions." Often, the actual time spent traveling by air far exceeds the time required for high-speed rail.
As China continues its reforms, the PLAAF is set to open more airspace for civil aviation, including airspace over Northwest China.
Therefore, I cannot say that Indian flights will never be able to use this airspace. Once the PLAAF permits civil aviation access to these areas, any civil aviation company—including those from India—will be able to apply for access.
However, this is a matter of Chinese state administration; it has absolutely nothing to do with the current "reckless behavior" of the Indian civil aviation sector.
