 On 13 March, Sukarno summoned Amirmachmud, Basuki, and Jusuf.Sukarno was angry that Suharto had banned the Communist Party of Indonesia (PKI) and told the three Generals that Supersemar did not contain such instructions.Sukarno then ordered that a letter be produced to clarify the contents of Supersemar but nothing ever came up apart from the copies that former Cuban Ambassador, AM Hanafi recollected.
