I have no idea if he is scheming with the the government or if he is simply trying to curry favour, but if you are a gwai lo (westerner) in China and want to get ahead for any reason (visas, job whatever), this is precisely what you would do. Whether its voluntary propaganda or paid propaganda, it's still propaganda.

You're making a false equivalence by oversimplifying things into symmetrical "sides." The Chinese state-owned media and propaganda apparatus have an established history of frequently spreading false or misleading claims for propaganda purposes. While Western media sometimes does get a story wrong or sometimes gets misled by their sources, they make a far greater effort to ensure objective accuracy, and are thus far more trustworthy.
For an example I recently experienced, I was confidently informed by a redditor that Infowars and Common Dreams are equally biased sources, and there's a deficit of critical thinking there that I just don't know how to communicate to someone. It's also common with believers in the fake news trope - it's not wrong that there's media bias, but that gets used as an excuse to equate mainstream media outlets to those that traffic in conspiracy theories.
I find this is too simplistic a view. The media often falls in with the government's foreign policy objectives, playing up foreign enemies, presenting their own government's interests as completely reasonable but "adversarial" countries' interests as illegitimate.
If you were to go by American media, the invasion of Iraq was a mistake based on faulty intelligence, while Russia's annexation of Crimea was a grave attack on the international order. Never mind that the invasion of Iraq caused an incomparable amount of human suffering, violated a central principle of international law (the illegality of wars of aggression), and was provably based on lies. The New York Times itself played a key role in pushing the WMD story and promoting the case for war.
