Reuters, New Delhi :U.S. President Barack Obama weighed in on one of India’s most sensitive topics as he wound up a visit on Tuesday, making a plea for freedom of religion to be upheld in a country where relations between Hindus and minorities have come under strain.Obama made no direct reference to Prime Minister Narendra Modi’s Hindu nationalist Bharatiya Janata Party (BJP), whose rise to power last year has emboldened some Hindu groups to assert themselves in a country with a history of religious strife.”Your Article 25 (of the constitution) says that all people are ‘equally entitled to freedom of conscience and the right freely to profess, practice and propagate religion’,” Obama told a townhall address to mostly young Indians in New Delhi.”In both our countries, in all countries, upholding this fundamental freedom is the responsibility of government, but it’s also the responsibility of every person.” Modi’s rise to power has emboldened right-wing activists to openly declare India a nation of Hindus, posing a challenge to its multi-faith constitutional commitment. About a fifth of India’s 1.27 billion people identify themselves as belonging to faiths other than Hinduism. Modi has warned lawmakers from his own party to stop promoting controversial issues such as religious conversions and to focus on economic reforms.Obama bonded warmly during his three-day trip with Modi, who until a year ago was persona non grata in Washington and was banned for nearly a decade from visiting the United States after deadly Hindu-Muslim violence in a state he ruled in 2002.The U.S. president’s visit has been widely seen as a bid to forge a relationship that will help balance China’s rise by catapulting democratic India into the league of major world powers.In his speech on Tuesday, Obama described the relationship between India and the United States as potentially “one of the defining partnerships of the century”.On Monday, he became the first U.S. president to attend India’s annual Republic Day parade, a show of military might that has been associated with Cold War anti-Americanism.Obama’s presence at the parade signals Modi’s willingness to end India’s traditional reluctance to get too close to any big power. Instead, he is seeking close ties with them all, even as he pushes back against China and take sides on other global issues.During the visit, the two sides sealed a clutch of deals to unlock billions of dollars in nuclear trade and deepen defense ties, and Obama pledged $4 billion in investments and loans to release what he called the “untapped potential” of a partnership between the world’s largest democracies.Most significant was an agreement on issues that, despite a groundbreaking 2006 pact, had stopped U.S. companies from setting up nuclear reactors in India and had become one of the major irritants in bilateral relations.Obama said the United States would stand first in line for the trade and investment opportunities that will spring from the economic reform drive under Modi. “America wants to be your partner in igniting the next wave of Indian growth. As India pursues reforms to encourage more trade and investment, we’ll be the first in line,” he told the townhall.
