China's armed forces actively provide medical care and aid to developing countries, and participate in international medical exchanges and cooperation, thus strengthening friendship and mutual trust with them. From 2010 to 2011, PLAN's hospital ship Peace Ark visited five countries in Asia and Africa and four countries in Latin America to provide "Harmonious Mission" humanitarian medical service. In 193 days the voyage covered 42,000 nautical miles, and nearly 50,000 people received medical services. In recent years, the PLA medical team has also provided medical service to local people in Gabon, Peru and Indonesia while participating in joint humanitarian medical drills.
