Similarly, no one cares about China kidnaping girls from neighboring countries to force them into marriage/prostitution in China. But people care a lot when China force gaming companies to censor their games and ban western citizens playing western games in a western country because they write “Free Hong Kong” in the chat.
>Most people couldn’t care less about what happens outside their borders unless the country responsible also do things that impact their life
The US is the country responsible here. US military commanders have said that the war in Yemen would end tomorrow without US assistance, and the US declared war on Afghanistan.
It also adds great frustration/anger when western companies fight for human rights in USA while they stay silent on China’s human rights issues (and even censor western citizens voicing support for them).
I have not heard these allegations of slave labor surrounding these internment camps. Maybe you're thinking of US prisons.
>The fact that their treatment feels equivalent to the holocaust makes it even worse
I'm still not defending China here, but their actions seem limited to cultural genocide not actual genocide. The US treatment of Muslims in Yemen is far worse.
