The Four Asian Tigers, Four Asian Dragons or Four Little Dragons, are the economies of Hong Kong, Singapore, South Korea and Taiwan, which underwent rapid industrialization and maintained exceptionally high growth rates between the early 1960s and 1990s. By the early 21st century, all four had developed into high-income economies, specializing in areas of competitive advantage. Hong Kong and Singapore have become world-leading international financial centres, whereas South Korea and Taiwan are world leaders in manufacturing electronic components and devices. Their economic success stories have served as role models for many developing countries, especially the Tiger Cub Economies of southeast Asia.
