"This provides a great investment opportunity for foreign companies, including those from Korea," Patil, who is on a three-day visit to South Korea said.
"In expanding and modernising our roads, highways, airports, sea ports and railways, we will require investment from foreign entities and firms.
"We look forward to greater participation in this endeavour by Korean companies," she said inaugurating a business interaction organised by Korea Chambers of Commerce.

"In India too, you spotted the economic opportunities long before others, and this first-mover advantage has enabled Korean companies to reap great profits in our country.
"Hyundai, Samsung and LG are household names in India today," the President said.
