India, especially West Bengal could deepen its people-to-people ties with neighbour Bangladesh, said Ambassador Riva Ganguly Das, former Secretary-East in the Ministry of External Affairs, while pointing out that in the official domain, collaboration between the two governments had been strengthened significantly in all areas, in recent years.Ganguly Das in an interaction with PTI on Tuesday, suggested that there can be joint theatrical productions and ballets, collaborative writing of books and works on Rabindranath Tagore between people who share a common culture and language.With a 4,096-km-long border, it is quite natural that there will be issues between India and Bangladesh.
