Every other article on the fact repeats this. Nearly a dozen citations and it's all just news articles about the same story.
I tried searching for the UN committee on racial discrimination tabled documents but couldn't find anything.
Is there any serious estimate of the number of people actually interned in these camps or is it all a game of Chinese whispers (pun not intended)
I have witnessed firsthand how indifferent mainlanders are to these things but think the original comment has merit.
Where's the actual non biased numbers?
I looked at that page, it doesn't seem to support the claim there are "millions of Muslims in a camp".

There was a link next to the 1 million figure in that article to a US Senate bill, which says "The purpose of this Act is to direct United States resources to address gross violations of universally recognized human rights, including the mass internment of over 1,000,000 Uyghurs and other predominately Muslim ethnic minorities in China..."
..but no source for that figure. From the article you linked to, it does sound like a horrific situation.
Can you source this (rather outrageous) claim?
