After his retirement as a minister in 1978, Sadli became widely regarded as one of the most senior policy-oriented economists in Indonesia. He remained a key adviser to Soeharto, he fostered his many links in business circles, and he became an active economic journalist. As an economic commentator Sadli made important contributions to public policy discussion in Indonesia throughout the 1980s and 1990s and until the time of his death. Because he was so well known and respected he could chide or praise almost anybody in public life at will, and he often did so with gentle good humour in the numerous columns that he wrote for the Indonesian publication Business News and other Indonesian publications. He was one of the first senior figures in Indonesia to become openly critical of the Soeharto regime. The most consistent theme in his public commentary was the need for good economic policy. Sadli took a close interest in international economic affairs as well. He often participated in seminars and conferences about economic affairs in meetings in Asia. He was appointed several times, in 1981 and again in 1987, as an expert member of international panels to undertake strategic reviews of the role of the Asian Development Bank in Asia. Sadli died quietly at the home where he had lived for many years in the suburb of Kebayoran in South Jakarta on 8 January 2008. He is survived by his wife, Professor Saparinah Sadli, who is a leading figure in Indonesia for her work in the fields of psychology and women's rights.
