China's yearly budget is around 6bil USD, India is around 1-2 bil USD, can you tell me how your Indic math came to this conclusion.
The 1+B budgets are coming up only recently. Add the budgets of all the years, you won't get much since they are much smaller.
And a direct comparison is pointless because China's space industry is run like a corporation under the PLA and includes other aerospace systems as well, including drones.

China divides space expenditure by channeling it through various corporations and research labs, dozens of them. So you won't get an actual figure that we can compare to.
At least India properly divides civilian and military space budgets.
Remember, Chinese space research was interrupted by cultural revolution for 10 years. Btw, there is nothing wrong with importing and absorbing technology, it is just the Indic holier than thou attitude which irritates people. Whether India can absorb the technology remains to be seen since China is at least 10 years ahead and currently has the most accurate clock on earth.
Making atomic clocks isn't really 'difficult'. What's most difficult is spending money on it.
The fastest computer, the most accurate clock, those are no different from getting the most Gold medals in the Olympics, they don't contribute to nation building as much as you think. Whether an athlete came 1st or 8th, there's no difference in the way they lived their lives.
What's important is efficient utilization of resources. No point having the tallest building in the world if it's empty. Instead get smaller buildings that you can afford, that others can afford and make do with those. It's not glamorous, but gets the work done.
What's the point of getting the most accurate atomic clock when less advanced, significantly cheaper generic ones give you all the accuracy you need? What do you want to do, provide navigation to insects?
It has research value, so be satisfied with that. We will start comparing once India's space budget manages to reach even 10% of China's. What ISRO has achieved with their meagre budget is frankly quite incredible.
Our monkey is orbiting Mars right now.
