Britain also set up a "resettlement" programme that provided a model for the US's Strategic Hamlet Program in Vietnam. During the Malayan Emergency, 450 new villages were created and it is estimated that 470,509 people – 400,000 Chinese – were interned in the resettlement program. A key British war measure was inflicting collective punishments on villages where people were deemed to be aiding the insurgents. At Tanjong Malim in March 1952 Templer imposed a twenty-two-hour house curfew, banned everyone from leaving the village, closed the schools, stopped bus services and reduced the rice rations for 20,000 people. The latter measure prompted the London School of Hygiene and Tropical Medicine to write to the Colonial Office noting that the "chronically undernourished Malayan" might not be able to survive as a result. "This measure is bound to result in an increase, not only of sickness but also of deaths, particularly amongst the mothers and very young children". Some people were fined for leaving their homes to use external latrines. In another collective punishment – at Sengei Pelek the following month – measures included a house curfew, a reduction of 40 percent in the rice ration and the construction of a chain-link fence 22 yards outside the existing barbed wire fence around the town. Officials explained that these measures were being imposed upon the 4,000 villagers "for their continually supplying food" to the insurgents and "because they did not give information to the authorities".
