In the post-pandemic era, global power dynamics are experiencing significant changes, which are influenced by various factors, including economics, diplomacy and technology. One crucial aspect is the shift in economic power from the West to the East. Countries such as China and India increasingly dominate the international stage. For example, the Belt and Road Initiative launched by China has strengthened Beijing’s position as a global power, facilitated infrastructure growth, and strengthened trade relations with Asian, African and European countries. Meanwhile, the US remains important, but faces new challenges. The battle to set technology standards, especially in the fields of 5G and artificial intelligence, is becoming a fiercely competitive arena. Large technology companies, such as Huawei and Google, play a role in determining the direction of innovation, and this has an impact on countries’ foreign policies. Also, the rise of nationalism makes some countries more likely to choose isolation over openness in trade and diplomacy. The COVID-19 pandemic has also changed the way countries interact. Countries are starting to realize the importance of health sovereignty and economic resilience. International cooperation on vaccination, such as COVAX, shows that collaboration remains important, even amidst geopolitical tensions. The global health system needs to be strengthened to face possible future pandemics and achieve balance in equitable vaccine distribution. Apart from that, climate change is one of the big challenges that the international community must face. The Paris Agreement demonstrates a global commitment to tackling carbon emissions. The emergence of discussions about the energy transition and sustainability has become part of the national strategy. Countries that are able to lead in green innovation, such as renewable energy, will gain financial and diplomatic benefits on the international field. In the military field, competition between the great powers is increasing. High defense budgets in countries such as China and Russia are in the spotlight, and military maneuvers in the South China Sea add to tensions. Defense diplomacy is important to reduce the risk of armed conflict. Overall, global power dynamics in the post-pandemic era reveal much deeper complexities. Traditional and new powers compete to exploit their respective advantages to dominate the international arena. Factors such as technological innovation, environmental sustainability, and global health are key considerations in state power strategies. Adaptation and collaboration skills will be key in facing these challenges.
