International forensic science organizations (associations) include the International Forensic Strategic Alliance (IFSA), the International Association of Forensic Science (IAFS), and others. Since its establishment in 2004, the International Forensic Strategic Alliance has expanded into a multilateral partnership alliance of six operating regional forensic science networks and three strategic partners, as its collaborative capabilities and international influence growing. This paper introduces the basic information of the International Forensic Strategic Alliance and its members. Using the Asian Forensic Sciences Network (AFSN) and the Senior Managers Australian and New Zealand Forensic Laboratories (SMANZFL) as examples, it analyzes the connections and distinctions between alliance members, including the topics of interest at the past five annual conferences, as well as similarities and differences in the focus areas of forensic science networks in different regions. This paper also reviews China’s relationship with the International Forensic Strategic Alliance, focusing on the development trends of forensic science domestically and internationally, and looks ahead to the prospect of China’s participation in international forensic science organizations (associations), with the aim of providing insights for promoting the internationalization of forensic scien ce in China.
