The "west" faces a relative decline, which is something to celebrate.* And I can hardly blame the Chinese government for taking an assertive position or for capitalizing on weaknesses in their perceived adversaries. But China faces some structural problems just at the time when the western powers are starting to reevaluate some fundamental assumptions of the last 40 and 75 years.
All around this sounds like a net good all around. Yes, even the repressive activities of the Chinese government I believe will moderate, as the US has become less thrusting in its own imperialism.
* Edit: I say this as someone born in the "west", living in the USA right now. Too much imbalance leads to stagnation, both in company policies (i.e. corporate monopolies) and geopolitics.
