TOKYO -- Japan is struggling to find a winning formula for its defense exports, as evidenced by drawn-out negotiations with India over the sale of its amphibious US-2 aircraft.
Tokyo has long hoped to sign a contract for the search and rescue seaplane, which would mark the country's first major defense deal. But after five years of discussion with India, no breakthrough is in sight, experts said, hampering Prime Minister Shinzo Abe's vision of becoming a proactive contributor to peace.
