At least 16 China-based institutions, including Asian Infrastructure Investment Bank (AIIB) and People's Bank of China (PBoC), have got permanent registration as foreign portfolio investors (FPIs) in India. While AIIB is a multilateral development bank, which has got India as a member too, PBoC is China's central bank. Other registered FPIs in India include the National Social Security Fund (NSSF), a government-run investment fund established primarily to provide a reserve of funds for China's social security system.
