I am not Chinese and i don't get paid to post my opinions. And Whataboutism can be used when its valid.
Let me get this straight : You're Canadian and this thread is about America and China. You don't like the human rights in China so you want America another country that has a dark past regarding human rights to collapse China? Would you support a war with U.S vs China?
I don't think that anybody in the United States, Canada, or elsewhere, wants the US to "collapse" China. This isn't about war or military conflict at all, and nobody in the US or China is remotely close to going to war or any sort of military intervention. Hell, The Trump Administration's recent antagonism with China and Huawei isn't even based on human rights abuses in China, they've notably left that out of their trade negotiations entirely -- something that me and others have been critical of the Trump Administration for. The State Dept. had raised the issue of persecution of religious minorities in China in ~2017 when trade negotiations began, but they seemingly dropped that issue over the last year ... If I had a hunch it's because the Administration learned that it was Muslim minorities being persecuted, and they dropped that issue so it didn't interfere with trade negotiations. I think that's a cowardly decision of the Trump Administration and par for the course for them, as the Trump Administration has continually turned its back to human rights violations around the globe.
When I bring up human rights abuses in China, like children being turned into orphans because their parents read them the Qur'an at night (which has been documented by the New York Times and Guardian), or family members of Chinese ex-pats being "disappeared" by a police state (similarly well documented), I don't do so with the ends of justifying a military conflict. I do so to bring light to something that a lot of people just generally don't know about.
Ideally, for me, I'd like trade negotiations between the US and China (which, btw, the US and China have a tremendous amount of concurrent trade) to have contingencies for improved human rights in China, especially for religious minorities. This isn't even a tall ask. I wouldn't expect for China to dismantle their surveillance state, that'll never happen and it's unrealistic. But, China did not crack down on Muslim minorities ~15 years ago, at least, it wasn't widespread bordering on genocide as it is today. My goal would be that by bringing these uncomfortable topics up, it helps motivate people to encourage the American government to use its economic leverage in China (which, the US and Europe has tremendous economic leverage) to encourage the Chinese government to stop persecuting religious minorities.
My skepticism with Huawei is more far reaching, but more personal. I'd actively oppose contracts in my home state that we might make with a company like Huawei to implement the eventual 5G rollout in the US. I think this is a valid concern of the state. Huawei has proven to be a disingenuous technological partner in the past, and I don't really care what they do in ... China, the Philippines, Brazil, or Ecuador, but I would actively petition my state against partnering with Huawei to implement wireless infrastructure where I live. It can't be trusted, the threat to Chinese ex-pats in America is too great, and at the end of the day, I'd rather my state partner with a company from Korea, Japan, Europe, or the United States ... Paying more for the rollout, but with a stronger partner that doesn't have a dubious track record of contributing to the surveillance and crackdown of Chinese dissidents. That's why I won't buy Huawei devices, either. I work with Chinese ex-pats and Chinese citizens living abroad in the US, and I don't want my device to unwittingly be used by the Chinese surveillance state to track the patterns of Chinese citizens outside the country ... It's just not something I'm willing to be a part of if I know it happens (which it does, though right now, not internationally ...... that we know about)
This isn't just about governments for me either. I was very critical of Google for "secretly" partnering with China to eventually bring Google search back to China. When Google pulled Google search out of China a decade ago, I really gave them a lot of praise. That was a force for good, a good decision for them, that they wouldn't compromise on values for the huge paycheck of doing business in China. Since then, the paycheck has been too alluring and their relationship with China had normalized, so they started developing a censored Google search with China. I get it, there's billions of dollars for them doing that and they're going to miss out on this because Baidu or WeChat or any other company will just fill that void for them and happily comply with Chinese government censorship, but I'm still critical of Google for starting to compromise their values for the payday.
