The Khmer Rouge's military forces remained divided into differing zones and at a July military parade Pol Pot announced the formal integration of all troops into a national Revolutionary Army, to be headed by Son Sen. Although a new Cambodian currency had been printed in China during the civil war, the Khmer Rouge decided not to introduce it. At the Central Committee Plenum held in Phnom Penh in September, they agreed that currency would lead to corruption and undermine their efforts to establish a socialist society. Thus, there were no wages in Democratic Kampuchea. The population were expected to do whatever the Khmer Rouge commanded of them, without pay. If they refused, they faced punishment, sometimes execution. For this reason, Short characterised Pol Pot's Cambodia as a "slave state", with its people effectively forced into slavery by working without pay. At the September Plenum, Pol Pot announced that all farmers were expected to meet a quota of three tons of paddy, or unmilled rice, per hectare, an increase on what was previously the average yield. There he also announced that manufacturing should focus on the production of basic agricultural machinery and light industrial goods such as bicycles.
