Ashe walks at the Mahatma Gandhi memorial after paying flower tribute at Rajghat in New DelhiBy Nate Raymond and Joseph Ax NEW YORK (Reuters) – U.S. authorities charged a former president of the United Nations General Assembly, a billionaire Macau real estate developer and four others on Tuesday for engaging in a wide-ranging corruption scheme. John Ashe, the U.N. ambassador from Antigua and Barbuda who was president in 2013, was accused in a complaint filed in federal court in New York of taking more than $1.3 million in bribes from Chinese businessmen, including developer Ng Lap Seng. In exchange, Ashe told the U.N. secretary general that a yet-to-be built multibillion-dollar U.N.-sponsored conference center in Macau was needed.
