Disaster diplomacy bears both a feature of normative values and an orientation of realpolitik. Germany is playing a major role in disaster assistance and international cooperation on disaster relief. As an important form of foreign strategy, disaster diplomacy has played a positive role in the rise of contemporary Germany. This article uses disaster as a basis for analyzing the path of disaster diplomacy in the realization of national interests. Under the path of “interactive relations”, Germany takes advantage of the window period of disasters to make up for its relations with the other major powers, promote relations with opposing players in key geopolitical games, and has achieved a breakthrough in its influence in the areas flooded with geopolitical conflicts among competing major powers. Under the path of “institutional layout”, as a first step, Germany has achieved growth in its power within the existing disaster prevention and mitigation system by catering to the others’ initiatives or taking advantage of its special status, and promoted institutional norms in the Balkans, the Middle East, North Africa and other peripheral zones to highlight German dominance in the form of “compliance with the institutions” while seeking for realizing the overall value of the West. In addition, based on the civilizational and shaping characteristics of disaster relief, Germany manages to minimize international criticism, “create disaster diplomacy institutions” in Africa, the Indo-Pacific and other politically emerging regions and countries,  export governance models and enhance its international influence. Focusing on its own pragmatic interests, Germany strives to expand its strategic space and actively competes with the other major powers, but follows Western values at key points. The strategy of disaster diplomacy is in line with the reality of Germany’s flexible foreign politics and accelerates its national resurgence.
