Which broad food category does Wikipedia use for jiaozi?

Wikipedia classifies jiaozi as a dumpling.

Jiaozi are Chinese filled dumplings made by wrapping ground meat, vegetables, or other fillings in a thin dough skin. The wrapper is sealed around the filling, and the dumplings may be boiled, steamed, pan-fried, deep-fried, or baked. That broad classification distinguishes them from categories such as soup, noodle, or curry.

Jiaozi are especially important in northern Chinese cuisine and are traditionally associated with Chinese New Year. Their shape resembles the silver and gold ingots used in imperial China, so they are linked with wealth, prosperity, and good fortune. Families may prepare them together and serve them with dipping sauces containing vinegar, soy sauce, garlic, or chili.

Gyoza is the Japanese adaptation of jiaozi, while mandu is the Korean name for a related dumpling family. These foods can look similar, but their wrappers, fillings, cooking methods, and seasonings vary by region.

A useful distinction is that “dumpling” describes the broad food category, while jiaozi identifies a particular Chinese style within it. Pan-fried jiaozi are sometimes called potstickers in English, but that cooking style does not make them noodles or soup.
