NEW DELHI (AP) — India’s Prime Minister Narendra Modi will meet President Barack Obama in Washington in September during a visit aimed at restoring strained relations between the two countries.

Modi told U.S. Deputy Secretary of State William Burns on Friday that he accepted an invitation from Obama.

According to a statement from his office, Modi said ties between the two democracies would be a powerful force for peace, stability and prosperity in the world.

Relations between India and the United States have been strained by the arrest of an Indian diplomat in New York in December over charges of visa fraud. Other irritants include U.S. concerns over alleged online piracy and intellectual property rights violations by Indian businesses.
