"With just 1.25 per cent share at USD 2.6 billion of South Korea's USD 215 billion worth total overseas investments till 2012, India figures quite low on the list of favoured investment destinations for South Korean companies".
The study highlighted that there is vast scope to boost India-South Korea trade in services like information technology (IT), information technology enabled services (ITeS), communications, banking, insurance, education, broadcasting, tourism and healthcare.
