That's the worst negotiating proposal I have ever seen. Not even Donald Trump would make such a deal...China can use this to extract concessions from Japan, if Japan wants power then support them for UNSC membership, in return for a return to pacifism, defensive posture and a recognition of past atrocities, in short Japan should make up for it’s past security abuses, it should resolve it’s current security issues with it’s neighbors.
Same tactic can be applied to India.
That's like selling hypersonics technology to the US for the promise of the US being peaceful. Absurd
