The IISS Asia Security Summit: The Shangri-La Dialogue (SLD) is a "Track One" inter-governmental security conference held annually in Singapore by the Bahraini-funded think tank, the International Institute for Strategic Studies (IISS). The dialogue is commonly attended by defence ministers, permanent heads of ministries and military chiefs of mostly Asia-Pacific states. The forum's name is derived from the Shangri-La Hotel in Singapore, where it has been held since 2002.
