When Mrs. Corazon C. Aquino became president in 1986, she appointed Dr. Soliven to represent the Philippines in the United Nations Educational, Scientific and Cultural Organization (UNESCO) in Paris, France. It was here that she was elected a member for the Executive Board, the highest governing body of UNESCO. In discussing the UN priority of literacy projects for Asia, Latin America and Africa, Amb. Soliven would often mention to the Director-General and members of the board how the Montessori System has worked so well in the Philippines for all Social classes of children as well as adults. Her colleagues, former Prime Minister of Australia, Mr. Whitlam; Amb. Wagner de Reyna of Peru, Dr. Zhao of China, Amb. Aboussouan of Lebannon and Mr. Cosmapodoeus of Greece were touched by her constant reference of Dr.Maria Montesori who championed for the cause of the child.
