India, China and others, including African countries, only object to the dehumanizing way ICE treats the deportees. Other than that they don't object to their people being deported - these countries also deport those who enter their countries illegally.

"Nigerians and other Black nationalities are being 'secretly' deported."
Not true! Even from the time of Obama it's been public knowledge that Black folks, especially Haitians, were being deported 'en masse'. I've posted about it here.
LOL. thats why Obama was known as "deporter-in-chief" - he was given that title for the large number of Haitians he was deporting!
