After asking the Reserve Bank of India (RBI) to be consistent in its approach toward special economic zones (SEZs), Commerce Minister Kamal Nath has now sought the Prime Minister's intervention to ensure clarity in the policy."The Prime Minister is looking at it. I have brought it to his notice," Nath said when asked whether RBI's directive to commercial banks to treat exposure to SEZs as realty projects would not deter prospective developers."The industry must take it up with the RBI," he said at a function organised by the export promotion council for EOUs and SEZ units."There are some real concerns, which the government will address but there are also some imaginary concerns. SEZs are the engines of growth and the government will not allow the regime to be sabotaged," he said.
