Free trade is about more than removing protectionist trade measures, but about making true international collaboration possible through the free movement of capital, goods, and to some extent labor; and the knowledge that comes along with the above transfers.
"In the wake of a new free trade pact and nuclear negotiations between India and Japan, the two countries will launch 24 green cities in the proposed Delhi-Mumbai Industrial Corridor (DMIC). The green cities will have optimized energy supply, 24-hour potable water supply, bicycles and walking tracks, and water and waste recycling systems. Preliminary work has begun on pilot projects in 7 green cities that will be part of the DMIC, which spans six Indian states. The first of these cities will be in Gujarat. The cost of the 5-7 year project is in the range of US $50bn - 90bn."

According to the igovernment article this information was taken from the DMIC is being designed as a potential "global manufacturing and trading hub," which would hopefully provided much needed jobs. Additionally they green cities have larger geopolitical implications as Japan seeks to open Indian markets to counter China's regional influence.
