Abstract: China's rise on the global stage, the most prominent feature of its current diplomacy, is the wider establishment of strategic partnerships with other countries. The Chinese partner's foreign policy also reflects the transformation of its foreign relations and development model. At present, in the international academic literature and policy discussions, although the exploration of the establishment of China’s partner diplomatic relations has begun, it has yet to fully analyze its deepening partner diplomatic relations, which still needs further discussion. The research theme of this study focuses on China's mode for deepening its partnership diplomacy, especially focusing on Xi Jinping's strategic model after taking power. Against this background, this study conducts a comprehensive and systematic analysis to explore China’s external partnership, and analyze the characteristics, categories, theoretical basis, current situation, and specific conditions and difficulties faced by China ’s Belt and Road Initiative With challenges and development prospects.
