Historically speaking, he's right. China has never had an expansionist foreign policy.
Tibet, the Philippines, and Taiwan would like to have a word, not to mention Chinese military action in support of its North Korea puppet state, and wars with Vietnam and India.
The one we live in, where they are constantly surpassing international law in international waters in the South China Sea?
The one we live in, where they are constantly rattling sabers at South Korea and Japan when it comes to military expansion?
The one we live in, where they brutally cracked down on Hong Kong when they did not abide by the 50 year one country two systems deal, not even making it half of the way through the agreed period?
The one we live in, where there is constant threat to Taiwan?
It may have been a lazy post you're responding to, but anyone that is paying attention to this topic enough to talk about it is going to either say 'Of course China is imperialist, the same as every other global power' or take some sort of tankie approach to justify it.
