Cross-border cooperation is aimed at helping all parties involved materialize a certain common goal. When it is the question of economic development with a view to make it sustainable, the stakeholders involved need to act in complete harmony and cooperation. Bangladesh is a small country with limited natural resources and a huge number of unskilled/skilled human resources. It has now become eligible to apply to United Nations for being recognized as a Developing Country, leaving behind its status of Least Developed Country (LDC). Formal recognition may be there in 2024 with the further enhancement of performance under three criteria i.e., per capita Gross National Income (GNI), Economic Vulnerability Index (EVI) and Human Resources Index (HRI). Foreign cooperation is urgently needed for Bangladesh to accelerate the transition. Also needed is a comprehensive sustainable development plan with its proper implementation in all sectors of the economy so that people of Bangladesh can enjoy the benefit of this elevation. Undoubtedly, this transition has to address many challenges and there will be prospects as well. Sustainable development will not occur unless Bangladesh can make sure that its development partners around the globe are willing to cooperate for mutual benefit. There should be a win-win situation for all. This international conference looks forward to have an in-depth analysis of all such issues pertaining to the core theme, “Sustainable Development through Cross-Border Cooperation”.
