Standing in the way are strict U.S. rules governing export of defense technology, including International Traffic in Arms Regulations (ITAR). Ely Ratner, assistant secretary of defense for Indo-Pacific affairs, has stressed the need to break down barriers to technology sharing with allies and partners, including India. But one congressional aide said efforts to speed technology sharing with India would face "an uphill battle" both in the U.S. Congress and at the U.S. State Department, where officials have a specific obligation to protect U.S. technology. "There are concerns about (technology sharing) in the Australia context and there would be more concerns in the India context," he said. Rick Rossow, an India expert at Washington's Center for Strategic and International Studies, said approval processes for advanced defense technology transfer were "onerous but not impossible."
