India will also advance but China is growing at a faster rate with an economy that is much larger. If this trend continue, which almost no one predict that it will change, than China will be more advance than it is today.
As I mentioned, Russian and Western European technology is ahead of China now but is likely that China will surpass them. This is because Europeans like to fight among themselves in addition to fight with Americans and Russians. Russians, after a big stall in the 90s, has to rebuild its momentum. This provide an opportunity for China to surge ahead of Russia and Western Europe.
If India continue to rely on Russia and Western Europe for military hardware, its going to find out that the imported technology doesn't have any real advantage over the Chinese domestic ones.
