Recent developments in international relations demonstrate complex and often unpredictable dynamics, characterized by shifts in global power, cooperative multilateralism, and new security challenges. One of the most striking trends is China’s increasing influence on the world stage. The “Belt and Road Initiative” (BRI) concept encourages large investments in infrastructure in developing countries, strengthening connectivity and market access. This increase has raised concerns among Western countries, especially the United States, which feels threatened by China’s dominance. On the other hand, diplomatic tensions between the US and Russia have heated up again with the Ukraine issue. Russia continues to demonstrate its military might, while NATO strengthens its presence in Eastern Europe. European integration has also faced challenges, with the UK having split from the European Union, while some member states are questioning the future of the integration project. The issue of climate change is also increasingly dominating the international agenda. The UN Climate Change Conference (COP) seeks to encourage countries to commit to reducing greenhouse gas emissions. Countries such as Iceland and Denmark are leading the way in the renewable energy transition, while developing countries are struggling with adaptation and financing for climate change. In addition, the COVID-19 pandemic presents new challenges in international relations. The uneven distribution of vaccines is creating tensions between developed and developing countries, and highlighting global inequalities in health access. World health authorities, such as WHO, are seeking to increase cooperation between countries in facing greater global health crises in the future. In Southeast Asia, the ASEAN organization is seeking to increase economic and political integration amid regional tensions stemming from territorial claims in the South China Sea. Initiatives to address cyber security and free trade issues are the main focus, in line with increasing cooperation in the digital economy. Conflicts in the Middle East remain a significant source of tension, with the situations in Syria, Yemen and Iraq not yet completely stable. Iran’s role as a regional power and its relations with Sunni Arab states are complex issues, shaping geopolitics in the region. Trends in the spread of new technologies, such as artificial intelligence and cyber security, also influence international relations. Countries are trying to utilize technology to improve national security and military capabilities in an increasingly digital world. Competition between the US and China in the field of technology highlights the need for clear global regulations on the development and use of technology. Active participation in international forums is increasingly important. Countries rely on public diplomacy to build their image and strengthen their influence. Social media is becoming a new information battlefield, and countries must adapt strategies to counter propaganda. Another important aspect is a paradigm shift in dealing with global issues. Agendas such as sustainable development and human rights are increasingly becoming an integral part of foreign policy. Countries are aware that collaboration at the international level is key to addressing cross-border challenges. Thus, recent developments in international relations create a more complex landscape, requiring closer cooperation among countries to address increasingly pressing global challenges.
