Abstract
The conflict between the United States and China in the Far East has had significant implications for the balance of power and regional security. This study examines how the U.S.-China conflict affects Iran’s national security, particularly in the military domain. The main hypothesis suggests that intensified military competition between the U.S. and China leads to increased military cooperation between Iran and China and the development of Iran’s defense capabilities. In this context, Iran has sought to enhance its national security against external threats, particularly U.S. pressures, by strengthening its naval forces in the Persian Gulf and the Gulf of Oman and advancing its military technologies. This research employs a qualitative analysis of documents and academic articles. The findings indicate that through military cooperation with China and expanding its military presence in strategic regions, Iran has been able to enhance its deterrence capabilities. However, this trend could also lead to heightened international pressures and increased tensions with the United States.

Introduction
The conflict between the United States and China in the Far East is one of the most significant geopolitical developments of the 21st century, with profound implications for the global balance of power and regional security. This rivalry extends beyond the economic sphere, encompassing political, military, and security dimensions as well. The Islamic Republic of Iran, as a key player in the Middle East, has been directly and indirectly affected by these developments and has reassessed its national interests and security in light of this conflict. This study aims to examine the impact of the U.S.-China conflict on Iran’s national security, particularly in the military domain. The main hypothesis is that intensified military competition between the U.S. and China will lead to increased military cooperation between Iran and China, as well as the advancement of Iran’s defense capabilities.

Materials and Methods
This research employs a qualitative analysis of documents and academic articles. Data for this study have been gathered from various sources, including academic publications, military reports, and documents issued by international organizations and research institutes. These sources provide a comprehensive analysis of the military, security, and geopolitical changes resulting from the U.S.-China conflict. Additionally, qualitative content analysis has been used to extract relevant data and assess the impact of this conflict on Iran’s military policies and strategies. The objective of this method is to uncover the relationships and implications of the rivalry between these two global powers for Iran’s regional policies and defense capabilities.

Discussion
The U.S.-China conflict in the Far East has evolved with increasing military and political competition in various arenas, particularly in the South China Sea and the Pacific Ocean. On one hand, the U.S. seeks to curb China’s influence by strengthening military alliances and expanding its presence in strategic areas. On the other hand, China is working to mitigate threats and reinforce its position by enhancing its military capabilities and expanding its diplomatic relationships. This rivalry has had significant effects on other countries, particularly Iran.
As a key nation in the Middle East, Iran is strategically positioned to capitalize on these competitions. In recent years, under economic and political pressure from the U.S., Iran has sought to strengthen its relations with China. One of the key aspects of this relationship is military cooperation. Given its reliance on Middle Eastern energy resources and raw materials, China views Iran as a strategic partner, while Iran seeks to counterbalance the void created by U.S. and Western pressures through expanded military and economic collaboration with China.
One of the most significant ways Iran has benefited from this cooperation is through the enhancement of its military capabilities. By developing military technologies, particularly in missile and drone systems, Iran has aimed to bolster its defenses against external threats, primarily from the U.S. Military cooperation with China has provided Iran with access to advanced technologies, enabling improvements in its defense capabilities.
Additionally, Iran has sought to strengthen its military presence in strategic areas such as the Persian Gulf and the Gulf of Oman, as these regions play a crucial role in national security and the protection of economic interests. In the naval domain, Iran has made significant efforts to expand its presence in international waters. The country has increased both the quantity and quality of its naval fleet to enhance its deterrence capabilities against external threats. The Iranian Navy’s presence in sensitive and strategic areas, including the Persian Gulf, the Gulf of Oman, and even the Red Sea, underscores Iran’s determination to protect its interests against regional and international threats.

Conclusion
The U.S.-China conflict in the Far East has had direct and indirect effects on Iran’s military and security policies. The intensification of military competition between these two global powers has created opportunities for Iran to enhance its national security by increasing military cooperation with China and developing its defense capabilities. Despite pressures from the U.S. and Western countries, Iran has been able to leverage this situation to strengthen its military capabilities. However, the expansion of military ties and Iran’s growing military presence in strategic regions could lead to heightened international tensions and increased political and economic pressures from the U.S. and its allies.
Furthermore, this conflict has increased Iran’s need to strengthen its diplomatic and military relations with other nations, including Russia. Nonetheless, expanding military cooperation with China remains a crucial strategy for Iran in countering external threats, particularly from the U.S. Iran must carefully manage the development of these ties and the enhancement of its defense capabilities to maintain effective deterrence against international threats and pressures.
In conclusion, while the U.S.-China conflict has presented strategic opportunities for Iran, the potential consequences must be approached with caution. Increased regional and global tensions, along with intensified economic pressures, could pose new challenges to Iran’s security and military policies.
