Wang Yi's speech was a reference to the political system. Since you quoted him, I thought that you had read it already, but if you need some more context, here is a passage from Reuters:

> The two countries should not seek to change each other, said Wang. "China cannot and will not become another America," he said, adding that a socialist system was suited to China and the choice of its people.

To be clear, that sentence you alluded to is saying that China's political system has not fundamentally changed in the past 30 years. It is still in its top-down authoritarian form that lacks the legitimacy to rule, unlike one provided by an electoral mechanism. On the other hand, forcing a change has not been a prerequisite for the West to engage with China during the same period.

To challenge a perceived status quo, the burden of proof is usually on the challenger. If you have evidence that refutes the common understanding of China as a political entity that is vastly different from the US, please provide them here instead of merely offering a rebuttal of the "common place generalizations" type.

By the way, I assume you understand that not every comment is intended to make a case.
