clearly you dont have an iota of knowledge regarding UNSC,
PRC became member of UNSC in 1971, earlier it was Republic of China<Taiwan> which was the permanent member.
In late 1950s & 1960s, western countries including Russia was in support of awarding UNSC seat to India, instead of PRC getting the
seat when Republic of China<Taiwan> was not able to foot the bills.
But stupid Nehru blinded in hindi-chini bhai bhai rhetoric, declined the seat and asked US and other powers instead give the seat to communist China<PRC>, Nehru was a blunder to India, stupid shit was living in fool's paradise and was thinking himself as a leader of NAM movement.
But I am pretty sure you chinese wont be educated in these things. Propoganda CCP propoganda
