Astronomy in Asia has continuously developed. Local wisdom in many Asian countries reflects their interest in astronomy since the historical period. However, the astronomical development in each country is different which depends on their cultures, politics and economics. Astronomy in some Asian developing countries such as China and India are well-developed while some other countries especially in south-east Asia, with some supports such as telescopes, training, experts etc. from some developed countries, are trying to promote relevant research in astronomy as well as use astronomy as a tool to promote scientific awareness and understanding for the public. Recently, a new national research institute in astronomy, called the National Astronomical Research Institute of Thailand (NARIT), with a 2.4-metre reflecting telescope has been established in Thailand. One of the major objectives of this research-emphasis institute would aim at a collaborative network among South-East Asian countries so as to be able to contribute new knowledge and research to the astronomical community.
