Co-operation between the two countries in various fields has improved in the last decade.
Security issues though remain the focus of ties between the two countries.
It was the coming to power of a coalition headed by the right-wing BJP in India in 1998 that dramatically changed relations between the two nations.

The BJP shares the Israeli Government's perception of a growing threat from Islamic terrorism.
Extra security teams have been placed in Delhi
There have been suggestions within both countries that - along with the United States - they should formulate a common strategy to combat Islamic terrorism.
When in 1999, India and Pakistan fought a war over the Kargil heights, Israel not only opened its ordnance depots to India, but provided photographs from its military satellites.
In recognition of Israel's military assistance, Indian Home Minister and a leading right-wing ideologue LK Advani visited Israel in 2000.

The 11 September attacks against the United States strengthened this perception.
India has provided a long shopping list of defence items to Israel.
There have been angry protests in India against Mr Sharon's visit
A defence expert, Cmde Uday Bhaskar, said India's needs in fighting terrorism and militancy could be met by Israel, which has expertise in surveillance and electronic warfare.

The Indian Government considers Israel to be a credible defence supplier.
After years of stalling the sale of the Phalcon anti-missile radar system to India, Washington recently approved its sale.

Now India wants Israel's assistance in forming an anti-terrorist squad.
The Indian home minister is expected to ask for Israeli expertise to raise a 3,000-strong rapid deployment anti-terrorist force.
For decades, India was shy of forging relations with Israel, fearful of Arab opinion.
Now - in the backdrop of tense Middle East situation - Mr Sharon's visit has become controversial.
But the Indian Government has made it known that its Arab policy will not be a hostage to relations with Israel.
Last week, the Palestinian Foreign Minister, Nabil Shaath, was invited to India to convey Delhi's commitment to an independent state of Palestine.
Certain political groups, Muslim organisations and non-governmental organisations have decided to hold protests against Mr Sharon's visit.

The name of the hotel where Mr Sharon is staying has not been made public, and extra security teams have been stationed in central Delhi.
