WASHINGTON (AP) — The U.S. brought a trade complaint against India Monday over a solar energy program it says discriminates against American manufacturers, adding another wrinkle to a bilateral relationship strained by the recent arrest and strip-search of an Indian diplomat.

It is the second time in a year that Washington has requested dispute settlement consultations with India over the program that it contends violates World Trade Organization rules by requiring suppliers use Indian-manufactured solar cells and modules.
