State conflict in Southeast Asia is a complex phenomenon and is rooted in the region’s long history. Since the ancient kingdoms, such as Majapahit and Sriwijaya, to the colonial and post-independence periods, various conflicts have colored interactions between tribes, religions and countries in this region. One of the most significant conflicts in Southeast Asian history is the Vietnam conflict. After the Indochina War and the war against the US, Vietnam was unified in 1975, but the impact of the war is still felt today. A series of social and economic upheavals hit countries experiencing war. It spread to Laos and Cambodia, where the Khmer Rouge ruled and caused a genocide, which left deep scars in Cambodian society. This problem continues with humanitarian disasters involving refugees and social unrest. In Indonesia, the conflicts in Aceh and Papua are rooted in dissatisfaction with the central government. The Free Aceh Movement (GAM) is fighting for independence, while separatism in Papua is triggered by issues of injustice and abuse of human rights. Local communities often feel alienated from distant powers, fueling tensions between the government and citizens. Malaysia faces challenges from Malay, Chinese and Indian ethnic groups, who often compete economically and politically. These tensions led to the racial riots of 1969, which required the government to be proactive in regulating inter-ethnic interactions in order to maintain stability. Thailand has also experienced internal conflict, especially in the south, where Muslim separatist groups are fighting for greater autonomy. Tensions between the government and the Muslim community have given rise to worrying acts of violence, creating an atmosphere of uncertainty in the region. In the Philippines, armed conflict with groups such as the Moro Islamic Liberation Front (MILF) and Abu Sayyaf has been going on for decades. Peace efforts have been made, but a comprehensive solution remains difficult to achieve. Dissatisfaction with the Manila government adds to the fog in the Muslim Mindanao region. Myanmar is in the world spotlight with the Rohingya crisis caused by ethnic and religious conflict. Violence against the Rohingya forced hundreds of thousands of people to flee to neighboring countries, creating one of the worst refugee crises in modern times. The strong government system and military rule remain the main obstacles to a just settlement. In conclusion, state conflicts in Southeast Asia reflect a history filled with tension, discontent, and struggles for political and economic rights. Efforts to achieve a peaceful resolution require intergovernmental cooperation and increased attention to human rights to prevent further violence.
