The rapid growth of East Asia, with China at its centre, has attracted globalattention. Many authors have emphasised the emergence of regional productionsystems and the spread of high rates of growth across a large number of Asianeconomies. Nevertheless, the East Asian regional production system has notbenefited all countries in the region equally. The more advanced Asian economies(Hong Kong, Singapore, South Korea and Taiwan) and the ASEAN-4 economies(Malaysia, Indonesia, Thailand and the Philippines) have a very different economicrelationship in China compared with the poorer countries of the Greater MekongSubregion (Cambodia, Laos, Myanmar and Vietnam). While the former havebenefited from complementarities with China, supplying parts and components tolargely export-oriented assembly plants, the latter are selling raw materials andresource-based products to China.
