Interesting. In 1992 we were in a terribe balance of payment crisis & all your lock & stock politicans were against reform, you know the typical IMF/World Bank conspiracy theories (Ya we've had our share of that too). 'Devaluaing the Indian Rupee is like devaluing India's pride' and such nonsense.
By then and in the next few years China's reforms were very extensively discussed. I think that by 1992 you had sufficiently proved your system works. And ya, I'm aware of Jiang Xemin's second thoughts and Deng's tour shoring up support for the reforms. That was quite historic.
Well, China did not fully devalue RMB until 1994 (8.62) which was th lowest and pegged against $ in 1997 (8.27).
I don't think it was that Jiang Zemin was having a second thought about the reform himself, it was that there was not enough support from the party, and he has not consolidated enough power within the party to fight those oppositions until Deng stepped out. After that Jiang's support for Deng helped himself to consolidate the power in the government and the party.
