The government is willing to be flexible on the limit of 5,000 hectare land area for special economic zones (SEZs), and the cap could be removed if circumstances permit, Commerce Minister Kamal Nath said today."In future, should a proposal come that looks at an area that may be larger, we are willing to look at it," Nath told reporters today."Right now, we have certain set of rules based on certain set of circumstances. They (circumstances) may change in future once we have a rehabilitation policy... We will look at it. It is a part of the Act and not rules," he added.There is a land ceiling in SEZs now and the cap remains, he said when asked to comment on Reliance Industries' comment that the current rules were not fool-proof.Reliance would be adversely affected by the limit of 5,000 hectares as it is already acquiring land for two SEZs spread over 10,000 hectares each in Haryana and Maharashtra.
