As India's Ministry of External Affairs has described it in the past, the Delhi Declaration of 2006 was a watershed moment in the history of bilateral ties between the two countries.
In January 2006, Saudi's King Abdullah was a guest at the Republic Day parade. The agreements under the Delhi Declaration included a whole host of issues, ranging from increasing trade, a strategic energy partnership, and active cooperation to fight terrorism.

Four years later in 2010, the then Indian Prime Minister, Late Manmohan Singh, visited the Saudi capital, leading to the Riyadh declaration, which raised their cooperation to a strategic partnership covering security, economic, defence and political areas.
Prime Minister Narendra Modi has added to the efforts aimed at strengthening ties with Saudi, one of India's third biggest oil supplier. Modi has visited the country twice in the last 11 years, and hosted the Saudi ruler, Crown Prince Mohammed bin Salman, once in 2023.
The two leaders have met eight times since Modi became the Indian Prime Minister in 2014.

In 2023, the two countries—along with the US, UAE, France, Germany, Italy, and the European Union—agreed to build the India-Middle East-Europe economic corridor (IMEC).
In an interview with Arab News in April 2025, PM Modi described Saudi as "one of India’s most valued partners — a maritime neighbor, a trusted friend and a strategic ally." During the visit, Saudi diplomats thanked India for its support for invitation extended to Saudi Arabia to join BRICS.

Other investments include Daawat Foods, LT Foods Limited health-tech startup Healthifyme as well as $700 million in wind and solar projects in Gujarat and Rajasthan.
The two countries are negotiating a bilateral investment treaty, which the United Arab Emirates (UAE) has already signed. There are an estimated 2.7 million Indians living in Saudi Arabia.
However, the defence tie-up betweeen India and Saudi Arabia is very young
