To a query on the status of alliance formations for Lok Sabha polls, he said a decision on it will take more time since polls were expected in the state in the last phase only.
He, however, indicated Congress was open for alliances with DMK and DMDK.
Congress voted for DMK in the Rajya Sabha polls despite DMDK leader Vijaykant's plea for support.
"As for Vijayakant, he has regards for Congress and likewise, we too have the same for him. People think an alliance of DMK with other parties would be strong. As for Congress, we never say no to anyone."
Brushing aside opinion poll results, which favoured Modi and BJP, he said, "You have to see what questions are being asked and to whom?"
Natchiappan, who is the Minister of State for Commerce and Industry, wanted the Tamil Nadu Government to present the Project Report for the proposed monorail project as early as possible and pledged the Centre's support for it.
He said the officials of the Japan International Cooperation Agency (JICA), which the state government had approached for financial assistance for the project, said they were awaiting the report to proceed further.
