PRC Influence on the US-Saudi Alliance Since 2011

China's invasion of the Persian Gulf and the Middle East as a whole is taking place against the backdrop of a global strategic rivalry by the United States. The United States is one of the most influential players in the Middle East and is still considered the "protective umbrella of the Middle East." In addition, military relations between Saudi Arabia and China, especially in terms of arms sales, provoke problems in relations between the United States and Saudi Arabia and can become one of the key indicators of the directions of bilateral relations. China's interference in the security sphere in the Middle East, especially China's intention to implement a 5G network in the region, cannot but worry the United States. The US-Saudi alliance is still quite strong, but now China is also seeking to strengthen relations with Saudi Arabia and strengthen its position in the region. Thus, both the PRC and the United States have their own interests in the Middle East and compete for influence at the same time Saudi Arabia achieve its goals using the best partner. Key words: USA, China, Saudi Arabia, Middle East, international relations.
