Washington ? Seeking firmer footing for U.S.-India relations, President Barack Obama tried Tuesday to calm India’s fears about Asian rival China, salving bruised feelings in the world’s largest democracy with an elaborate state visit and assurances of India’s “rightful place as a global leader.”

“The relationship between the United States and India will be one of the defining partnerships of the 21st century,” Obama declared — twice — during a news conference with Indian Prime Minister Manmohan Singh.

The two appeared before reporters in the East Room after an elaborate morning welcome ceremony that was moved indoors by rain and about two hours of private talks in the Oval Office. The daylong White House extravaganza in India’s honor was capped with the day’s most buzz-worthy event: the first state dinner of Obama’s presidency.

The black-tie party for more than 300, featuring a mostly vegetarian meal of curry prawns, aged basmati rice, eggplant salad, lentil soup, potato dumplings and other delicacies served under a giant tent on the South Lawn, was Washington’s premier must-have invite. Menu, decor and attendance details — each designed to celebrate Indian culture and delight Indian guests — were kept tightly held until just hours before guests arrived in their finery.
