Naidu, however, did not clarify if he was in favour of a separate Telangana or a united Andhra Pradesh, saying he just wanted "justice" for both.
"We want justice for the people in both areas," he said.
Asked which side his party was on, he evaded giving a straight answer. "If you have two children, who would you chose?"
Naidu accused the Congress of dividing the people.
"Congress party is playing total politics on the issue. They don't care if the common people suffer, they want to collect maximum votes," said the former Andhra Pradesh chief minister.
Naidu said Andhra Pradesh is in a state of "immobilismo" (Italian for being immoblie).
"I am using Italian language because it may be easier for the Congress government here to understand," he said.
He complained that the central government held no discussions with other political parties on the decision.
"Why are they not calling an all-party meeting? Is this an internal decision of Congress?" he questioned.
"Democracy means if there are problems, they have to be debated, discussed and there must be some deliberations and ultimately they have to find some solutions."
"Ruling Congress has forgotten all these things. They are not finding any solutions. On the other hand they are creating problems," he said, adding that people in Andhra Pradesh are losing confidence in the political system.
