"The main objective of his visit is to consolidate the progress made (by India and US) in diverse areas such as economy, energy, environment, defence and security, and to intensify cooperation for the future," he said.
The BJP leader was talking to reporters during his brief halt at Harni airport here on way to Mehsana city in North Gujarat.
Important announcements will be made during the PM's three-day US visit, he said without providing details.
The US Congress has been a source of strength for the Indo-American strategic partnership, he maintained.
Realisation of the full potential of Indo-US economic partnership has been a key priority for both countries and the progress achieved in this regard is reflected in the increased investment flows, Madhav said.
The BJP leader later left for Mehsana, about 200km from here, where he will attend an event marking two years of the Modi Government.
