The expansion of urbanized cities has started to engulf rural areas, making the urban–rural boundary less and less conspicuous in China. Urban encroachment has led to a rapid shrinkage of the rural territory as the rural–urban migration has increased due to better job opportunities and living standards in the urban cities. Urban villages, governed by a rural property rights mechanism, have started to emerge sporadically within urbanised areas. Various approaches, such as state-led, developer-led, or collective-led approaches, to redevelop these urban villages have been adopted with varying degrees of success. This paper uses a case-study framework to analyse the state–market interplay in two very different urban village redevelopment cases in Guangzhou. By an in-depth comparative analysis of the two regeneration cases in Guangzhou, which started within close proximity in terms of geographical location and timing, we are able to shed light on how completely different outcomes may result from different forms of state–market interplay.

YEH Centre of Urban Planning and Environmental Management The University of Hong Kong Pokfulam Road, Hong Kong SAR [email protected] and [email protected] Submitted to International Journal of Urban and Regional Research First Submitted on 22 July 2003 Revised and Re-submitted on 10 August 2004 Final revised submitted on February 2005 City Repositioning and Competitiveness Building in Regional Development: New Development Strategies of Guangzhou, China Jiang XU and Anthony G.O. YEH* Abstract Competition among cities for mobile capital in the 21st century has intensified. Urban hierarchy of a region is undergoing transformation, where economic fortunes vary markedly among different localities. In China, these global forces and regional restructures have caused a relative economic decline of some historically powerful cities, and have also brought about the emergence of new economic centres. In response to these forces, many Chinese cities have been driven into adopting a series of new competitive strategies, which seek to win back and build up their leading positions and competitiveness. To translate these strategies into concrete actions, local governments have promoted high profile and face-lifting projects and investments. The extensive new urban development in Guangzhou is a particularly interesting case. As the provincial capital of the Guangdong Province, and a historically central city in the Pearl River Delta Region, Guangzhou’s importance has recently declined. This paper attempts to reveal the general strategies and specific projects initiated by Guangzhou as important promotion devices in its revitalization program, and to examine the rationales behind them.

Breaking new methodological ground, David Graddol demonstrates how a study of public discourse – in newspapers, blogs, signs and advertisements in the urban landscape – can be used to monitor the complex changing role that English is now playing in education, employment and evolving social identities. Profi ling English in China: The Pearl River Delta River ling English in China: The Pearl Profi He argues that researchers need to distinguish between di erent levels of English profi ciency more sensitively and illustrates how the Common European Framework of Reference (CEFR) can be used as a research tool by sociolinguists. Profi ling English in China: The Pearl River Delta is intended as the fi rst of a series of books exploring the changing social, economic and educational contexts in which English is learned and used. David Graddol presents methods of inquiry which will be useful for researchers working in other parts of the world. The book will be essential reading for anyone seeking a wider understanding of the role of English in globalisation and economic development.

Island ports and island cities represented key sites of water-facilitated transport and exchange in the ancient Indian Ocean and South China Sea. Building our analysis upon a historical overview of the ancient Maritime Silk Road from the perspective of China’s Guangdong Province and the city of Guangzhou, we envision a millennia-long ‘Silk Road Archipelago’ encompassing island cities and island territories stretching across East Asia, Southeast Asia, South Asia, West Asia, and East Africa. Bearing in mind the complex movements of peoples, places, and processes involved, we conceptualise the ancient Maritime Silk Road as an uncentred network of archipelagic relation. This conceptualisation of the ancient Maritime Silk Road as a vast archipelago can have relevance for our understanding of China’s present-day promotion of a 21st-Century Maritime Silk Road as part of the Belt and Road Initiative.

If they were not levelled in the 1950s, the Red Guards of the Cultural Revolution (commonly dated 1966-1976) would have done the rest. There is, for sure, much evidence of destruction to support this general view, and the difficulty of access to archival materials does not make investigation easier. However, at a closer look, there are some cemeteries of foreigners extant (if “reworked”) and, more importantly, they are at times even integrated today into Chinese heritage preservation schemes.
