Saudi Arabia's King Salman bin Abdul-Aziz Al Saud gave Indian Prime Minister Narendra Modi a very warm welcome last weekend in a public tilt of Saudi policy toward New Delhi and away from its traditional ally Pakistan. Economic interests are part of the tilt, but so too is Saudi pique at Pakistan's refusal to back its military adventure in Yemen.

Modi and the Saudis signed five new bilateral agreements to improve relations, covering intelligence sharing on terrorism financing, increasing private investment and enhancing defense cooperation. Salman bestowed the King Abdul Aziz Order of Merit medal on the prime minister; it is the kingdom's highest honor and has never been given to a purely civilian Pakistani leader (although it was given in 2007 to President Pervez Musharraf, a general who ousted Prime Minister Nawaz Sharif in a 1999 coup). Modi in turn gave the king a gold replica of the Cheraman Juma Masjid mosque in Kerala, the first mosque in India, dating from the seventh century, and a symbol of trade between Arabia and the Indian subcontinent.

Just days before the visit, the United States and Saudi Arabia jointly announced sanctions against four individuals and two organizations in Pakistan involved in financing terrorist organizations, including al-Qaeda, the Taliban and Lashkar-e-Taiba. The joint announcement was unprecedented. Four years ago, the kingdom deported a senior Lashkar-e-Taiba official to India who had been involved in the 2008 Lashkar-e-Taiba attack on Mumbai, which was backed by Pakistani intelligence. Modi met with Crown Prince Mohammed bin Nayef, who is also minister of interior and the kingdom's top counterterrorism official.

Economics play a big role in the Saudi-India relationship. About 3 million Indians work in Saudi Arabia, almost half the 7.3 million Indian worker population in the Gulf states. Bilateral trade in 2015 was almost $40 billion and India imports a fifth of its oil from the kingdom. The Pakistani emigre population is about 1.5 million and trade was about $6 billion last year. Modi met with senior Aramco officials to discuss more energy and investment opportunities.
