Chidu switched to the 1500 m for the 1991 IAAF World Indoor Championships and the change brought her a bronze medal behind Lyudmila Rogachova and Ivana Kubešová. Her finishing time o f 4:06.27 minutes made her the third fastest indoors that season. Her first and only global outdoor appearance for Romania came at the 1991 World Championships in Athletics, but she could not progress beyond the 800 m heats. She was a guest performer at the Japan Championships in Athletics that year and topped the podium in the 1500 m. She missed a 1500 m medal by one place at the 1992 European Athletics Indoor Championships, losing to teammate Doina Melinte. She returned to that event for the 1994 edition. A gold medal came at the Balkan Athletics Indoor Championships.
