How does this alternative history benefit PRC? All the elite Indian diasphora couldn't stop US from siding with Pakistan for most of recent history, or prevent global supply chains from shifting to PRC for decades, or secure critical tech transfers to help India develop. Reality is diasphora tend to have very little control over foreign policy unless it already aligns with state interests (Jewish/Cuban lobby). Ultimately PRC would take increased Chinese (as in the country) global influence, by simply being 5x the size of India because "CCP baggage" allowed her to transfer, retain and coordinate more domestic talent, over increased Chinese diasphora influence in the US anyday. Functionally, CCP baggage didn't prevent plurality of foreign students being from PRC (again because 5x richer), which translates to knowledge flow back to PRC. Recent NBER study on Indian brain drain to US had some crazy figures like 90% of top 10, 60% of top 1000, 36% of top 100 Indian IIT rankers gets brain drained to US. That may be good for Indian influence in the US, but not for India. Meanwhile ethnically Chinese talent is flowing back to PRC because >4% of US being Chinese = not enough political power to prevent another red scare regardless. What's more benefitial for PRC, diasphora that also makes PRC stronger or diasphora that exclusively makes US stronger. It's the former. PRC extracts more benefits from diasphora with a few decades of successfully lobbying the much more influential US business interests.
