Anglos despise Chinese not because of their eating habits, but because they are Chinese. Even if Chinese had the most immaculate eating habits in the world, westoids will simply find something else to criticize.The image of Chinese is, using the most racist terms possible, is a short, dark skinned, bucktoothed godless gold digger infested by COVID that blowtorches dogs before eating them alive.
A way to combat that is through simple, common sense legislation that's already in the works or has already been implemented locally, educate the public about facts relating to other countries, and promote local biotechnology.
1. pass the anti animal cruelty law that's been discussed since 2009. this would disarm both the rhetoric from the right wing ("Chinese are inferior dog eaters!") and the libs ("Chinese are cruel to animals!"). Shenzhen and Zhuhai already banned dog eating, and Jinhua banned a dog meat festival. The one who banned it in Jinhua, Cai Qi, is now in the PBSC.
2. strictly enforce the wildlife laws. get rid of the bear bile farms. It really makes Chinese look backwards and weird.
3. fund education for the foreign public about animal cruelty and disgusting eating habits in their 'Asian allies' and themselves as a contrast. Examples: running endless articles on how Koreans eat millions of dogs, Japanese eat whales and dolphins, Indians drink cow piss, etc. The west goes apeshit over this stuff but so far, they're directing it entirely towards China and giving Koreans/Japanese/Vietnamese/Indians a pass.
4. encourage local biotechnology companies to produce high tech, non-animal foods to prevent them from being monopolized by the west and to reduce dependency on western imports that fuel animal agriculture.
5. promote Chinese religions. For example, give scholarships to foreigners who want to study religion like Buddhism and Daoism in China (even if its Christianity, they'll be studying Chinese Christianity). It's not expensive and let's be honest, a foreigner that wants to study Chinese religions, is already halfway to becoming a self paid wumao.
Religion and values are things that people will actually change their minds for. Proof: China provides halal food everywhere, despite Muslims being <10% population. China has sufficient hard power to avoid overt coercion, so time to start playing the soft power game.
Once you realize this, the answer to sinophobia becomes surprisingly obvious and simple: fentanyl. Lots, and lots of it.
