their large contributions. In addition, the government began to nationalize foreign-owned plantations and mines, investing in the industries of rubber, copra, and tin. However the facilities were noted to be ill-maintained, which ultimately harmed Indonesia's economy under Sukarno. The islands began to set up semi-autonomous governments until a rebellion finally broke out a year later, hindering production and devastating government revenues due to the loss of exports. Back in the United States, at an OCB (Operations Coordination Board) Luncheon on January 8, 1958, the memorandum for the record states: "Mr. Dulles gave a brief report on the latest developments in Indonesia. He referred particularly to indications that the Bandung Council proposes to establish a Free Government of Indonesia, and said that while he believes a move of this sort would be premature, there is little we can or should do to try and stop it. It was agreed it would be unwise to supply arms so long as the possibility exists that the government might become communist dominated." Nevertheless, the dissidents of Sumatra were anticipated to issue a demand for the establishment of an anti-communist government on February 7, 1958, threatening that any denial of this demand would lead to a rival regime. Noting the dissidents deep distrust of Sukarno, prior proposals for compromise coming from the Djuanda Cabinet were rejected outright. Dissidents supported the Indonesian diplomatic missions in various countries including Singapore, South Vietnam, Malaya, and Italy. Given their resistance to prior proposals, an intelligence memo indicated that the rival regime was poised to proceed regardless of Sukarno's response. As such, these negotiations were viewed as Sukarno's stalling tactic in order to avoid the formation of the rival regime. While the dissidents were poised to take action regardless of Sukarno's response to their demand, they still feared military attacks from Djakarta in the form of airstrikes. In addition, Djakarta was allegedly maneuvering to split the dissidents, specifically the group under South Sumatran commander Barlian. Propaganda to dispel the dissident movement was also alleged to have been in existence in an intelligence memo, as both Indonesia and the Soviet Union were branding the dissidents' movement as a U.S. plot to fragment and enslave the nation. On February 9, 1958, rebel Colonel Maludin Simbolon issued an ultimatum in the name of a provincial government, the Dewan Banteng or Central Sumatran Revolutionary Council, calling for the formation of a new central government.
