Tibet. Their ongoing border disputes with India. Island disputes along side their bullying of nearly every maritime neighbor in the region. Stationing destroyers outside of Australian cities as a show of force.

Plus, their current antagonistic relationship with Japan, where they make direct public threats to Japanese leaders who respond by seeking nuclear weapons.

They are currently probing for weakness in their neighbors because of territorial ambitions. Just because they don't invade countries on the other side of the world like the USA does, doesn't make them pacifists. They just have different goals.

yeah they really shouldn't be blockading their neighbors while claiming every country around them is their sphere of influence and openly interfering in their allies domestic politics while leveraging their size to force other countries to accept asymmetric economic deals...

Please spare us. China invaded Vietnam to protect Pol Pot while he was mass killing millions of innocent civilians. They have territorial disputes with over 10 countries, which they've been unable to decisively act on because those neighbors either have nukes (India) or are protected by a more powerful country (US). Not because their government is some benevolent entity. They're basically an authoritarian dictatorship that's kind of cornered at the moment (like Saddam after the Gulf War) but would kill a bunch of people and expand if the US wasn't around.
