The problem of developing countries arise primarily from the eternal question: why are some regions developing much faster than others? These reflections go back to ancient times, where already the world's ancient state of knowledge and consciousness divided countries and geographical areas into rich and poor, which was mainly related to the availability of raw materials and favourable conditions for agricultural development. With the diverse development of individual countries, much poorer regions than others began to emerge. Examples include Sub-Saharan Africa and Central and South Asia. It is the latter that seems to be extremely interesting because there is no denying that Asian countries have chosen their path of development, different from that of the West. While Taiwan, Singapore, Japan and South Korea have developed and continue to develop rapidly, countries like India, Afghanistan and Bangladesh are still underdeveloped in terms of economic and social development.?The improvement of the situation of these countries was to be influenced by their support by foreign capital. Most transfers were made based on development assistance, which can be provided as money transfers, provision of consumer and investment goods or expertise and advice. Although it has been provided for decades, it is worthwhile, in the face of a growing wave of criticism (especially its effectiveness and efficiency), to check whether countries recorded economic and social development thanks to official development assistance. To this end, a study on the impact of development assistance on social and economic development was conducted in a group of the 5 largest recipients of British development assistance in Central and South Asia (India, Afghanistan, Bangladesh, Pakistan, Nepal) using the grey incidence analysis method.
