Internal migration within Asian countries and international migration to, within, and out of Asia have been on the rise throughout the past decades. As types and pathways of migration, migrants' sociocultural and socioeconomic backgrounds, and their transnational and translocal trajectories become increasingly diverse, a majority of them move to cities. Diverging power geometries and relations are constantly negotiated and (re)produced in the sociospatial dialectic of the city. Through their individual and collective agency, assets, and knowledge, mobile subjects have become important agents in the (re)production of spaces in cities, whereas the socio-political and physical conditions of spaces frame their livelihoods, opportunities, and agency. Research on migrants' agency has intensified recently, but the specific modes through which agency operates in the socio-spatial dialectic still need to be conceptualised. We develop a framework that outlines different modes through which agents and space interact. The framework is exemplified through papers on case studies from Dhaka and the Pearl River Delta (PRD) that are part of this special issue. Dhaka and the PRD have been characterised by accelerated growth throughout the past decades, particularly due to the influx of rural-to-urban migrants, but they also receive an increasing number of international migrants. We conclude that through their diverse, multi-sited, and translocal relations and activities stretching beyond the receiving cities in a context of constant transformation, migrants' practices contribute to the emergence of a specific type of urban spaces that we delineate as transient urban spaces.

China p erspe ctiv es Sp ecial feature Reclaiming the Neighbourhood Urban redevelopment, citizen activism, and conflicts of recognition in Guangzhou BE TTINA GRANSOW ABSTRACT: This study examines social interventions into the everyday life of residents, families, and communities during a redevelopment project in an old town neighbourhood of Guangzhou. It further analyses how citizen activism unfolds in response to these redevelopment interventions. To better understand contention over the renewal of an old town neighbourhood-beyond negotiation of compensation for economic losses-the study is structured by a recognition-theoretical model of social conflict following Axel Honneth and Nancy Fraser.

The Pearl River Delta (PRD) with its strong focus on international export production has a higher concentration of NGOs that support migrant workers than any other part of China. To better understand mechanisms of inclusion and exclusion affecting migrants in the city and their organisations, this paper takes up Martina Löw's (2008) space-theoretical concept and her critical reference to Anthony Giddens' structuration theory showing how space can be interpreted as a duality of structural ordering and action elements. It asks whether these migrant worker NGOs can be seen as agents of change influencing the process of urban restructuring in the PRD and producing new urban spaces while negotiating with numerous different institutions on behalf of the workers. Based on a critical review of the literature, longterm participatory observation and expert interviews with NGO leaders and staff, it uses four examples-NGO office space, factory space, litigation space and hospital space-to argue that these NGOs are producing transient urban spaces that not only advocate labour rights but also serve broader processes of creating and transforming the mega-urban landscape of the PRD.

This paper links China's pattern of infrastructure lending to Latin America and the Caribbean (LAC) with China's own development experience in this regard. It raises the question whether Chinese infrastructure investments in LAC have the potential to promote sustainable development in the region. The paper consists of four parts. Part 1 outlines China's massive domestic infrastructure construction projects as a specific development strategy which has contributed considerably to the country's rapid internal development, but has simultaneously given rise to complex dynamics of social and environmental risk. Part 2 assesses the strategies involved in China's infrastructure investment in LAC. Part 3 identifies key actors involved in China-LAC infrastructure cooperation and how they relate to different ways of financing infrastructure projects. Part 4 focuses on policy guidelines for managing the social and environmental risks of infrastructure projects. The paper concludes that more research, more capacity-building, and new forms of multinational development cooperation are needed to strengthen the social and environmental policies associated with China's infrastructure investment in LAC countries, to help uphold existing social and environmental standards, and to extend project benefits more effectively to local communities and people.
