"World economy is slowing down. The US' growth rate is three per cent. In India, it is around seven plus per cent", he said.
The Minister said that earlier (in the UPA regime) there was policy paralysis, but now there is a dynamic leader. "A leader recognised in the world," he said.
"As per a survey, Modi will again be elected as Prime Minister. That is the mood of the nation", he said.
The visit of union ministers to various states to hold review meetings with ministers and officials was a new concept introduced by Modi. Centre and states must work together. "Team India is the concept", he said.
He said he came to Chennai to meet Chief Minister K Palaniswami and the ministers to hold a review meeting and to know the requirements of the state.
Naidu said he had conducted such review meetings when J Jayalalithaa was the Chief Minister.
