Nicaraguan President Daniel Ortega arrived in Tehran on Sunday for talks with Iranian leaders as Tehran seeks to boost ties with leftist Latin American critics of the United States.Ortega, a Cold War foe of the United States, was welcomed personally at Tehran’s Mehrabad airport by President Mahmoud Ahmadinejad, an unusual step indicating the warm ties between the two nations. Ahmadinejad visited Managua in January shortly before Ortega’s swearing-in as president and the two leaders announced the restoration of full diplomatic relations and the re-opening of embassies in each other’s capitals. “We will work together to put in place a world order based on peace and justice,” Ahmadinejad told reporters at the airport, reprising one of his favourite themes. “The two peoples have great capacities to put at each other’s disposal on the way to independence and freedom,” he added.
