Nationality, ethnicity, or culture can represent the actual country or continent, its people, its culture, or really anything that you personally associate with that area of the world. Consider what comes to mind when you think of that area and its culture, and the context in which it appears in your dream. For example, an object that is Chinese might represent Eastern culture, ancient origin, wisdom, philosophy, alternative medicine, or a particular person you perceive to be of Chinese origin whom you’ve interacted with lately, among other meanings.
