I struggle to understand the end goal of this sort of attitude. The sacrifice you would need to make to even remotely pressure China is orders of magnitude more than you could imagine. The last time a sanction actually worked was with Iran's nuclear program, which completely crushed their economy. That also required the most sophisticated cyberattack in history. Sanctions alone did nothing to stop Russia's annexation of Crimea, and that also caused Europe to suffer from expensive gas prices. China has a much large economy, so any equivalent sanction would be the largest drag on the economy since WWII. Also, keep in mind that any sanction use for humanitarian leverage is one less that we can use for geopolitical or economic leverage. The likelyhood that politicians would vote for meaningful sanctions to help Xinjiang is about as likely as voting for offering China $1 trillion to shut down their reeducation camps.
