The Asian–African Legal Consultative Organization (AALCO) is an international governmental organization formed in 1956, initially to serve as an advisory board to member states on matters on international law. It was an outgrowth of the Bandung Conference, held in Indonesia during April, 1955, which led to the establishment of the Asian Legal Consultative Committee (ALCC). In April, 1958, it changed its name to the Asian-African Legal Consultative Committee (AALCC) to reflect the growth of its membership beyond the African side of the United Arab Republic. Since 2001, it has been known by its current name, the AALCO, reflecting the growth of its international status; currently an intergovernmental organization having received a standing United Nations invitation to participate as an observer in the sessions and the work of the General Assembly and maintaining a permanent office at Headquarters.
In 2014, the AALCO established an Informal Expert Group on Customary International Law. That group adopted a set of comments on the work of the International Law Commission on identification of customary international law. Those comments and the report of the AALCO Special Rapporteur Sienho Yee are published on the website of the AALCO.
