New Delhi, Aug 25 (IANS): President Pranab Mukherjee Monday said the Indian economy has undergone major changes over the years and no policy can be considered relevant for all times.

Addressing a delegation of Indian Trade Service (ITS) officers, who called on him at Rashtrapati Bhavan, Mukherjee said: "That system is dynamic which has the flexibility to change with changing times. Therefore, India's policies should contribute in helping the flexibility and dynamism of the economy so that it grows.

The delegation consisted of eight probationers and 20 officers of ITS.

The president said foreign trade over the years has been playing an important role in the Indian economy.

"Exports have continued to be the major focus of India's foreign trade policy. With enhanced e-governance in Directorate General of Foreign Trade (DGFT) and the changing role of DGFT itself, the officers would now have to act as trade facilitators and not only as regulators," he said.

"Trade facilitation has to be carried out at every stage, from designing a scheme to granting of benefits to exporters through these schemes. As trade facilitators, the ITS officers would be able to give new impetus to our economic requirements," Mukherjee added.
