Buenos Aires, under the city administration of Horacio Rodríguez Larreta, has recently implemented an ambitious social and territorial integration project in Villa 31 and other low-income settlements within the city. The mayor and his team have circulated the project in prestigious universities and urban forums while talking about Buenos Aires as ‘a global city’. When discussing the design of this integration initiative, the mayor referred to London’s Borough Market, New York’s High Line and Medellín’s Parque Biblioteca. This paper examines the role of policy circulation on the change in discourse and practice towards low-income settlements in Buenos Aires, as well as its relation to the making of a world-class city. I argue that: (a) policy change has been the result of a complex assemblage of artifacts and individuals that mobilise successes, a process that is increasingly South-South; (b) the city government drew its inspiration from urban policies adopted by other cities, not only for the urbanisation project itself, but for approaches to internationalise the initiative; (c) Buenos Aires is using this project as an opportunity to world itself as an integrated city. By doing so, this research adds value to the policy mobility scholarship, since Latin American cities are not only worlding themselves through mega urban developments but also through the circulation of singular ‘world-class’ imaginaries.

在HoracioRodríguezLarreta市政府的领导下，布宜诺斯艾利斯最近在31号别墅和城市中的其他低收入住区实施了雄心勃勃的社会和领土融合项目。市长和他的团队在谈论布宜诺斯艾利斯为“全球城市”的同时，在著名的大学和城市论坛上散布了该项目。市长在讨论这项整合计划的设计时，提到了伦敦自治市镇市场，纽约高线和麦德林的公园图书馆。本文探讨了政策循环在布宜诺斯艾利斯低收入住区的话语和实践的变化及其对建立世界级城市的关系中的作用。我认为：（a）政策变化是动员成功的人为因素和个人的复杂组合的结果，越来越南南的过程；（b）市政府从其他城市采用的城市政策中汲取了灵感，不仅是为了城市化项目本身，而且是为了使倡议国际化；（c）布宜诺斯艾利斯正在利用该项目作为向世界展示自己作为一个综合城市的机会。这样一来，这项研究为政策流动性研究增加了价值，因为拉丁美洲城市不仅通过大型城市发展来实现自身发展，而且还通过奇异的“世界级”想象力的传播来实现自身发展。（c）布宜诺斯艾利斯正在利用该项目作为向世界展示自己作为一个综合城市的机会。这样一来，这项研究为政策流动性研究增加了价值，因为拉丁美洲城市不仅通过大型城市发展来实现自身发展，而且还通过奇异的“世界级”想象力的传播来实现自身发展。（c）布宜诺斯艾利斯正在利用该项目作为向世界展示自己作为一个综合城市的机会。这样一来，这项研究为政策流动性研究增加了价值，因为拉丁美洲城市不仅通过大型城市发展来实现自身发展，而且还通过奇异的“世界级”想象力的传播来实现自身发展。
