The development of international politics is currently at a dynamic stage, especially in facing various global crises. Climate change, the COVID-19 pandemic and geopolitical tensions have shaped a new landscape for relations between countries. This crisis not only affects world security and stability, but also encourages countries to seek joint solutions. First, climate change is a major issue in global politics. Countries are finding that environmental threats know no borders, prompting them to collaborate more closely on initiatives such as the Paris Agreement. Efforts to cut carbon emissions and make renewable energy a priority are now an important agenda, demanding clear and implementable agreements between countries. Countries such as the US and the European Union play an active role in leading these initiatives, while developing countries often demand compensation for the losses they suffer from climate change. Furthermore, the social and economic impacts of the COVID-19 pandemic are also accelerating changes in international politics. The global health crisis highlighted weaknesses in health systems and made clear the dependencies between countries. Countries are now focusing more on health security and stronger defense systems through international cooperation. Health ministers from various countries often meet virtually to discuss strategies for handling outbreaks and distributing vaccines fairly. Geopolitical tensions, especially between major powers such as the US and China, are heating up. Trade disputes and the Taiwan issue are in the spotlight, with each side reinforcing their positions. Alliances such as AUKUS between Australia, the UK and the US show how countries are trying to build joint strength to confront China’s dominance in the Indo-Pacific region. This is not just about military power, but also includes economic and technological influence. Apart from that, the shift in global power cannot be underestimated. The emergence of new powers in Asia, such as India and Indonesia, provides a new dynamic in international relations. These countries are starting to be recognized as important players in international forums and play a role in mitigating global problems. India, for example, has been active in global initiatives related to climate change and sustainable economic development. All these developments indicate the need for adaptation in global diplomacy. Public diplomacy is now becoming more important, where countries must be able to build a strong narrative to win opinion at the international level. Social media plays a big role in this, allowing information to be disseminated quickly and widely. Finally, awareness of the importance of inclusion in political decision making is also increasing. The voices of civil society and non-governmental organizations are now being given more attention in various international forums, creating space for more democratic dialogue. This is important in creating consensus among countries, especially when dealing with complex and multidimensional global issues. In facing this challenge, commitment to multilateralism becomes increasingly crucial. International organizations such as the UN and WHO must be strengthened to be able to deal with increasingly complex global issues. Certainly, this period will continue to witness rapid developments in international politics, pushing countries to think and act more strategically for a sustainable and secure future.
