Why is Indian FDI shying away from South Asia?

There have been promises of greater Indian investment in South Asia for a long time. A report produced by the Asian Development Bank (ADB) in 2007 argued that India would play a key role in investing in South Asia and this in turn will stimulate intra-regional trade in the region. The report made special reference to the rapidly growing Indian IT industry and identified it as a potential investor in South Asia. The ADB argued that business process outsourcing, knowledge process outsourcing, call centres and other IT related sub-contracting would shift to regional countries as a response to increased costs of doing business in India.
