But their behaviour towards Hong Kong, Taiwan, Tibet, Mongolia and the various neighbours in the South China Sea isn't exactly non-aggressive.
And might want to look into how they use debt to further their geopolitical aims around the world e.g. trying to build naval ports in the South Pacific. It's far more insidious and a long term threat to world stability than most people realise.
South America is littered with American interference, as is the Middle East (which is unstable precisely because of American interference), parts of Africa (Mobutu was propped up by the US, as was Museveni, Moi, PW Botha etc).
The US has destabilized vast parts of the rest of the world then complains about the same people immigrating into the US. The conflict in Nicaragua are a direct is a direct result of CIA activities there, the US reaction to refugees fleeing from a war caused by the US into the US is to build a wall.
The rest of the world hasn't been stable - it's just that their current actions break the monopoly the US has had on causing instability in the world - for the rest of the world, it's good.
The US has just been as hungry for natural resources, it's financed regime changes in Iran, Iraq (in the 50s and in the 00s), the rest of the world views the US as a net aggressor and a cause of war and death in their parts of the world.
China definitely isn't as overt as the US
Yes, what China does to its own citizen is immeasurably worse than what the US (currently) does to its own citizen. But that's not really relevant, because the leader of $(Country X) is not trying to emigrate to China.
The more relevant question is: how many non-Chinese regimes were overthrown by China in the past 100 years? (In other words, "What do they do with the data?", as you asked.)
