Dr. Andreas Wladis, Medical Director of the UN Division of Healthcare Management and Occupational Safety and Health, says technology matters, but proper medical screening, training and established protocols remain essential. More than 60 representatives from troop- and funding-contributing countries and UN agencies took part in a high-level workshop on UN peacekeeping in Changsha, capital of central China's Hunan Province.
