Recent developments in international relations reflect complex dynamics involving global politics, economics, and social issues. One of the most striking trends is the increase in multilateral cooperation post-COVID-19 pandemic. Countries are starting to realize the importance of collaboration in addressing global challenges such as climate change and public health. The COP26 conference and the global vaccination initiative are clear examples of these efforts. On the other hand, geopolitical competition between big countries, especially between the United States and China, is increasingly heating up. This rivalry spans a wide range of fields, from technology to trade. China is trying to expand its influence in the Asia-Pacific region through the Belt and Road Initiative project, while the US is trying to strengthen strategic alliances with its allies in the region. Issues of social injustice and human rights also dominate international discussions. Countries such as Myanmar and Iran have attracted global attention due to ongoing human rights violations. International organizations such as the United Nations (UN) have attempted to address these issues, although they have often been hampered by differences in political interests between the permanent members of the Security Council. Climate change is the main agenda in international relations today. Countries must commit to reducing carbon emissions and switching to renewable energy. The Paris Agreement signed in 2015 urges countries to contribute to achieving the goals and reducing the increasingly real impacts of climate change. In addition, attention to environmental issues has triggered the emergence of environmental diplomacy involving private companies and civil society. Technology also plays an important role in international relations. The cybersecurity crisis and the influence of social media in politics bring new challenges to countries. For example, cyber attacks targeting critical infrastructure are a problem that needs to be addressed collaboratively by countries. Additionally, the debate over regulation of big tech is growing, with a focus on data privacy and political influence. Global migration continues to be an issue that affects international relations. Conflict, climate change and poor economic conditions are causing increasing refugee flows. Countries such as the European Union face challenges in formulating fair and sustainable immigrant reception policies. This phenomenon also encourages increased dialogue between countries in managing migration in a more humane way. Additionally, international organizations continue to adapt to meet the needs of a changing world. Apart from the UN, regional organizations such as ASEAN, the European Union and the Arab League are trying to address current issues by formulating relevant policies. Aspects of public diplomacy are also receiving more attention to build a positive image of a country in international eyes. The latest developments in international relations are of course closely related to the paradigm shift in understanding global power. The world is no longer just determined by big countries, but also by non-state actors such as NGOs and multinational companies. Interdisciplinary approaches involving economic, cultural and technological aspects are increasingly important in the study of international relations. Thus, recent developments in international relations are a reflection of interrelated challenges and opportunities. A deep understanding of this phenomenon is very important for every individual and country to play an active role in shaping the future of a better and fairer world.
