Vietnam is not part of the
Four Asian Tigers. Hong Kong, Singapore, South Korea, and Taiwan are known as
the Four Little Tigers or Four Asian Dragons because of their highly
free-market and developed economies. These four countries were successful in
maintaining exceptionally high growth rates and rapid industrialization since
the mid ‘50s to ‘90s. All four had already developed into advance and high
income economies by the 21st century.
Hong Kong and Singapore are
now world-leading international financial centers while South Korea and Taiwan
are world leaders in manufacturing information technology. They currently serve
as role models for developing countries like the Philippines.
