Diplomatic relations between developing countries play a vital role in strengthening global positions and improving societal welfare. In this context, these countries often form strategic alliances to fight for common interests, including in the fields of trade, security and social development. One important aspect of diplomatic relations is cultural exchange. Through student and cultural exchange programs, developing countries can promote their national identity. For example, scholarship grant programs or arts festivals can create stronger ties between different nations. When people from different backgrounds interact with each other, it strengthens understanding and tolerance between them. International trade is also the main focus of diplomatic relations in developing countries. Many of these countries have abundant natural resources, which can be explored and utilized. Cooperation in trade not only improves the economy, but also provides wider market access. Through bilateral and multilateral agreements, developing countries can ensure that they gain fair benefits from global trade. In addition, security cooperation among developing countries is increasingly important. Especially in facing the same challenges, such as terrorism, drug trafficking and climate change. Through organizations such as the Gulf Cooperation Council (GCC) and SADC, these countries can share intelligence and strategies to maintain regional security. Involvement in joint military exercises is also a significant step to increase each country’s defense capabilities. Infrastructure development is also an important point in diplomatic relations. With support from more developed countries through aid programs, developing countries can develop the infrastructure necessary for economic progress. For example, building roads, bridges and other public facilities that are essential for the development of remote areas. Technology is another pillar in relations between developing countries. Investments in information and communications technology can accelerate business growth and reduce the digital divide. Developing countries often seek partnerships with technology companies from developed countries to increase their capacity. Collaboration in green technology also involves the transfer of knowledge and resources to address environmental issues. Social and humanitarian aspects are also part of this diplomatic relationship. Developing countries are often active participants in international organizations focused on human rights and social development. Cooperation in the fields of health, education and poverty alleviation is a promising focus, with countries sharing best practices to improve the quality of life of their citizens. Developing countries, through diplomacy, seek to address the challenges they face collectively. By supporting each other and sharing resources, these countries can create a better future for their people. Strong and productive relationships not only bring economic benefits, but also strengthen their position on the international stage.
