Asked why protests over land acquisition continued despite the Centre coming out with the R&R policy, Nath putthe ball in the court of the states.
"States must ensure what they are doing is acceptable to the people. There is no issue in so many states on SEZ at all," Nath said adding the land issue was not restricted to the SEZs but concerned all the industries.
For instance, the Tata project in Singur in West Bengal was not an SEZ but faced protests. "The Tatas' Nano project in Singur is not an SEZ....the same political party in Kerala is putting up an SEZ. There is the same party in West Bengal. What are they doing?" he said.
Ruling out any changes in the SEZ policy, Nath said "there is nothing wrong with the policy".
Nath contested the finance ministry's contention that there would be big revenue loss on account of the tax-free enclaves.
He said the ICRIER study commissioned by the finance ministry pointed to the contrary. "I have the report and it says that there is revenue gain and phenomenal economic activity through the SEZs. It says SEZs have been one of thebiggest engines of growth," Nath said.
He said over Rs 50,000 crore (Rs 500 billion) worth of investment has been made in the SEZs with direct employment of 150,000 people.
The government has so far given formal approval to 404 SEZs and notified 193 zones.
