You Indian like to make wet dream that Nepal and Bhuan to be Indian's states
, that's only possible if you're able to convince Japan and Vietnam to be Chinese's states...a lunatic claim will give you much credit on your statement.
As for Japan, it's already walking into the path of self destruction, sitting on the world most dangerious "
ring of fire" where earth tectonic plates are crushing each other to create volcanos and Tsunami, Japaneses could brag of their greatness during 80s and 90s for their cars and electronic industries, now is over taken buy China and South Korea...now these peoples are living in hopeless future, they're more depend on China's import than the other way around, Why we chinese want to take on a
sick man of Asia if we use their own term
. If they act nice with Chineses, maybe in the future we might allow some Japaneses to live in China when entire Japan is sunk or stroke by natural desaster.
And don't brag yourself so much about Indian and ASEAN or all my teeth will fall, we have more economy interraction with ASEAN countries thanks to chinese diaspora serving as trade link, India is so insignificant that the inclusion is just to give Indians some face saving
And for S.Asia, it's not first time India is trying to solve the issues but make matter worst, you have tried then failed, will try will fail again
...but China provide these SA nations a much better alternatives to solve their problems that's why we prevail.
