If Japan wants to hit China very badly where it will hurt it the most, Japan should more actively pursue DMIC corridor and invest more and more in manufacturing capacity building in India
.Chinas strength is not its Army or CCP, it is their exports which is earning them huge dollars which in turn they are putting in their defence and to threat almost all of its neighbouring countries
..Once its export growth stops and it sees downward trend, Chinese system and CCP will face the wrath of millions of its blue collar factory labours...
Wet dreams by a hidutva troll won't make it reality.
Lifting of Japan's self imposed arms embargo has more to do with the survival and revival of their own defence industry and economy than to do with keeping china at bay. The sino-japanese territorial dispute will be settled diplomatically as Tokyo Knows what's good for them. They not suicidal. And japan's need china now for their economy more than china need japan. SO Indian dreaming about Japanese alliance against their rivalry with china is only fooling themsleves.
