This paper focuses on the inner workings of Mao-era China's ‘foreign affairs’ system (waishi xitong): the complex, comprehensive web of bureaucracy woven after 1949 to monitor and control Chinese contact with the outside world. It explores one of the channels along which the People's Republic between 1949 and 1976 tried to project international, soft-power messages beyond conventional diplomatic channels: the inviting of so-called ‘foreign guests’ (waibin) on carefully planned tours around China, often with all or at least some expenses paid. Earlier accounts of this hospitality have evoked a machine of perfect control, carefully judged to manipulate visitors and rehearsed to ensure flawless performances by Chinese hosts. Using memoirs and Chinese archival documents, the paper discusses the attitude of top-level leaders to such visits, the way in which trips were prepared and planned, and the successes and weaknesses of the system. It argues that the People's Republic of China's hosting programme had a domestic as well as an international purpose. Although foreigners were the official target (and indeed, Maoist China's ‘techniques of hospitality’ garnered some rich international political dividends) the government also used the preparation for and execution of hosting duties to underscore at home the triumph of the revolution.

8 Lisa Foa, ‘Perché fummo maoisti: la Cina è un giallo’, Limes (1995), 237–8. Jon Rognlien, the scholar of Norwegian Maoism, confirms this view: interview by author, Skype (Cambridge and Copenhagen), 3 Feb. 2014. For an almost exclusively light-hearted take on the engagement with Maoism by French youth of the late 1960s and early 1970s, which again emphasises the playful, imagined nature of this enthusiasm, see Miller, Gerard, Minoritaire (Paris, 2001), 76123Google Scholar. He writes, for example: ‘It's impossible to understand the passionate interest in China that thousands of French teenagers of my generation felt if you imagine that we were in love with the idea of the iron fist. Quite the contrary: what dazzled us about Mao was his spirit of mischief, his insubordination. . .To me, Mao's China at the end of the 1960s was much more “olé-olé” [than the doctrines of the Trotskyites]. . .[D]uring these years there was frankly nothing better to do in France than to be enraged; and nothing better for the enraged than to be Maoist’ (79, 80, 97).

10 Over the past two decades, a plethora of memoirs of Mao-era China published in English, often focused on the political and xenophobic extremism of the Cultural Revolution, has powerfully influenced non-specialist understandings of this period of history: the best known and most successful has probably been Jung Chang's Wild Swans (1991).

11 Consider, for example, the rich secondary literature on the engagement with Maoist politics and culture within individual countries, particularly India, Nepal, Peru and France: Banerjee, Sumanta, In the Wake of Naxalbari: A History of the Naxalites Movement (Calcutta, 1980)Google Scholar, and India's Simmering Revolution (New Delhi, 1984); Adhikari, Aditya, The Bullet and the Ballox Box: The Story of Nepal's Maoist Revolution (London, 2014)Google Scholar; The Shining Path of Peru, ed. David Scott Palmer (1992); Wolin, The Wind from the East; and Davis, Belden, ‘French Maoism’, in The 60s without Apology, ed. Syres, Sohnyaet al. (Minneapolis, 1984), 148–77Google Scholar.

12 Paul Hollander, Political Pilgrims: Travels of Western Intellectuals to the Soviet Union, China and Cuba 1928--1978 (Oxford, 1981). As another example, consider Tom Buchanan's thorough but unilateral account of the links between China and British leftists, in East Wind: China and the British Left, 1925–1976 (Oxford, 2012), and a review by Qiang Zhai (a prominent archival historian of Chinese foreign relations during the Cold War) expressing reservations about the one-sided nature of Buchanan's treatment: ‘Buchanan's treatment would have been fuller if it had incorporated some coverage of Chinese reception and manipulation of the British Left. Buchanan would have presented his readers with an international history if he had examined how the Chinese, both the Nationalists and Communists, used foreigners, including the British Left, to “sell” their images and win international endorsement abroad.’ Available at: (accessed 12 Jan. 2015).
