By discussing the importance of martime power in the overall narrative of the Chinese socialism, this paper explores the potent connotations of creating and wielding such power in this new era. This study outlines the foundations of a theoretical system of harmonious maritime power that will be made a reality to support the development of China and the common interests of all human beings, which should be operated in consultation with other nations on a dialectical level. Futhermore, it also argues that China should adopt a new model of peaceful marine development, adhere to the basic principles of mutual benefit and win-win cooperation, implement the strategic task of enforcing the country and enriching the people through ocean development, as well as promote the overall development of the oceanic economy, marine science and technology, marine environment and maritime forces. Finally, this paper introduces the idea of transforming China into a new maritime power that is "strong, but not tyrannical", which require a new approach to maritime power development with Chinese characteristics featuring mutual benefits and sustainable development.
