We need to give a no nonse stand against China, because if we dont Chinese will sit on our head; actually they helped Pakistan with N-bomb; shows their negative attitude towards India.
China would improve unless they get thrashing for misadventure, infact border skirmishes with China- once we gave sound thrashing in late eighties.
We have excellant defence force- and N-blackmail wont work against-because Sanghai-Hong Kong are within our Su-30 jets tipped with missile.
