Recent developments in diplomatic relations between major countries show complex and varied dynamics. Relations between the United States and China, for example, continue to experience tensions in various sectors, including trade, technology and security. The Chip Act policy implemented by the US aims to limit China’s access to high technology, creating uncertainty in global markets. On the other hand, relations between Russia and China are getting closer, especially in the face of pressure from Western countries. This strategic partnership is seen in various aspects, including military and energy cooperation. Russia sells natural gas to China in significant quantities via the Gas Power of Siberia Route, demonstrating Asia’s increasing energy dependence. This has the potential to change the geopolitical map of Asia and Europe. The European Union is seeking to strengthen its ties with India and other countries in Southeast Asia in an effort to balance China’s influence. The free trade agreement between the EU and India that is being negotiated aims to increase economic engagement, with a focus on green technology and industrial sectors. This also signals a potential shift in global alliances. In the Middle East region, relations between Saudi Arabia and Russia also appear significant. Cooperation in OPEC+ marks a new collaboration in managing oil production for market stabilization. Both countries are seeking to reduce dependence on the US and strengthen their bargaining position in global energy deals. Apart from that, developments in diplomatic relations between small and large countries are also quite striking. African countries are starting to attract the attention of major powers such as China and the US, which are competing for increased influence on the continent. China’s Belt and Road Initiative is a clear example, with many infrastructure projects being built to strengthen connectivity. Technological advances also affect diplomatic relations. Cyber diplomacy is becoming increasingly important, with countries seeking to protect their digital assets while remaining in touch. Cybersecurity is being debated in international forums, indicating that this issue is increasingly becoming a major focus. In the context of climate change, major countries such as the US, China and the European Union are moving towards deeper collaboration to achieve carbon emissions goals. COP meetings have stimulated international dialogue and agreement, although implementation challenges remain. Finally, shifts in diplomatic relations cannot be separated from the influence of civil society and public opinion. Social media and instant news provide a platform for new voices, driving transparency and accountability at the government level. This creates a more interactive and responsive environment. Overall, diplomatic relations between major powers continue to develop in an increasingly complex context, reflecting broader geopolitical changes and global challenges that must be faced together.
