Since the collapse of the Soviet Union, China's military cooperation with Russia has become increasingly close. China has become an important **order** for Russia, and from the early 90s to 2007, China has introduced a large number of advanced Russian fighter jets, anti-aircraft missile systems and destroyers. However, with the rapid development of China's most advanced technology, its equipment has achieved self-sufficiency, and a variety of equipment has been exported overseas. 
China and Russia have their own characteristics in terms of strategic resource reserves. During World War II, Germany fought fiercely for the seizure of oil fields in the Caucasus, which fully demonstrated the importance of strategic resources. Since 1949, China has continuously strengthened its strategic resource reserves, covering grain, metal raw materials, petroleum, rare earth minerals and other fields. Russia, on the other hand, has a natural advantage in oil and other energy resources. In terms of military strength, the Russian Army has about 300,000 people on active duty, about 2 million in reserve, and about 46.5 million suitable for service. China's active duty is about 1 million, the reserve is about 10 million, and the suitable number of service is about 6200 million. In terms of the number of tanks, Russia has a large number of T-90, T-80 and T-72 tanks. China, on the other hand, is dominated by Type 99 99A, Type 96, Type 96A and Type 15 tanks. In addition, the number of infantry fighting vehicles in Russia exceeds 120,000 units, more than 4,000 units in service, mainly including BMP-3, BMP-2 and BMP-1 infantry vehicles. China, on the other hand, has about 8,500 infantry vehicles, including 2,000 Type 08 wheeled infantry vehicles and 2,300 04 04A tracked infantry vehicles. 
With the rapid progress of China's leading technology, the mutual influence and dependence of China and Russia in the military field are gradually changing. China's military modernization is not only reflected in the advanced nature of its equipment, but also in the innovation of military strategy and tactics. The squadron is working to improve its rapid reaction capabilities and long-range strike capabilities, which is fully reflected in the development of China's new generation of missile systems and unmanned aerial vehicle technology. In the future military competition, technological innovation will be the key. China's investment in areas such as artificial intelligence, quantum communications, and cybersecurity is gradually increasing, and the development of these technologies could revolutionize traditional military confrontations. At the same time, China is also actively exploring military applications in space and cyberspace, which will be a new area of military competition in the future. 
Although Russia still maintains its superiority in some traditional military fields, the limitations of its economic power have made it significantly lag behind China in the high-tech military field. Faced with this situation, Russia may seek more military-technical cooperation with China in order to compensate for its own shortcomings. Therefore, Sino-Russian cooperation in the military field will continue to play an important role in jointly addressing future challenges and maintaining regional peace and stability.
