The China of the 1970s was a communist dictatorship. The China of the twenty-first century is a one-party state without a firm ideological foundation, more similar to Mexico under the PRI than Russia under Stalin. But the measurement of the political and the economic evolution has not yet been completed, and is one of the weak points of the system.

In my view, there's no doubt that the Soviets had infinitely greater trouble holding their structure together than we did.

China has had a long and complex history and has managed to evolve its own culture for 4,000 years. It therefore not necessarily true that we know exactly what is best for the internal structure of China.

I do not know what will happen in China politically. I do know that it is impossible to maintain the communist system or probably even a strict one-party system when the economy becomes so pluralistic. Now, what form that takes and what institutions will evolve, I do not have a clear view about. I do not think the United States, as a general principle, ought to intervene in this.
