Books about India- especially interested in learning about anti-indian racism/prejudice among Asian countries

I've recently seen some very intense negative racist language used against an Indian man on Chinese social media. It reminds me of American racism against black people in its verbiage and vitriol, but as I can see that a lot of Chinese folks online don't grasp the full depth of America's history with racism and slavery, I know I have no clue about the history of China and India, Thailand and India, etc. and I'd like to learn. Bonus points if the book has an explanation about India's caste system/associated history/internal systems of racism. TIA!
