State conflicts in the 21st century arise from various complex factors that influence global stability. As the world becomes more connected, new challenges emerge, ranging from economic, political, to social issues. One of the main causes is rising tensions between major powers such as the United States and China, which is fueling territorial disputes and affecting international alliances. In addition, identity-based conflicts, especially those related to ethnicity and religion, are becoming increasingly significant. Cases such as the conflicts in Syria and Yemen show how internal divisions can trigger widespread violence. Refugees and mass migration also create challenges for surrounding countries, worsening social and economic conditions. Climate change is also a trigger for conflict. Many regions experience shortages of resources such as water and food, which causes tensions between countries. Vulnerable countries are often the targets of spikes in instability, exacerbating the problem. One solution to this conflict is multilateral diplomacy. This approach involves dialogue between countries that encourages cooperation and understanding. For example, international organizations such as the UN and ASEAN play an important role in conflict mediation. By uniting various interests, diplomacy can reduce tensions. Education also plays an integral role. Raising public awareness about the values of tolerance and cooperation can help prevent conflict. Educational programs that promote cross-cultural understanding can reduce the prejudices that often exacerbate the situation. The economy must be directed to address the inequalities that are a source of tension. Inclusive and sustainable development programs can reduce poverty and increase access to resources. Investments in infrastructure and innovation can create new jobs, reducing dependence on conflict. Today’s technology also offers innovative solutions, such as the use of digital platforms to disseminate accurate information and facilitate dialogue. Social media can be a powerful tool if used in a constructive way, supporting narratives of peace and collaboration. Finally, strict application of international law needs to be enforced to address human rights violations. A global commitment to these basic principles can create a safer and more stable environment for all countries. Applying a holistic approach that includes diplomacy, education, economic development, technology and international law can be an important step in overcoming state conflict in the 21st century. By understanding the root causes and involving all levels of society, it is hoped that the world can move towards more lasting peace.
