Are all tobacco companies of various brands state-owned enterprises?

First of all, let me correct a common sense mistake: there is no such thing as tobacco companies of various brands.

To answer the question directly, China's tobacco industry implements a management system of unified leadership, vertical management, and exclusive sales. Therefore, tobacco production, sales, and supporting product manufacturing enterprises are all state-owned enterprises.

China National Tobacco Corporation is a typical representative of two brands in one organization. The tobacco company (monopoly bureau) is mainly responsible for the sales of tobacco. The general naming method is "such-and-such Tobacco Monopoly Bureau (company)". There is no doubt that it is a state-owned enterprise. The "tobacco companies of various brands" in the question should actually be called "XX Tobacco Industry Co., Ltd.", which is mainly responsible for the production of cigarettes, such as Gansu Tobacco Industry Co., Ltd., which produces cigarette brands such as Lanzhou brand, etc. It is also a state-owned enterprise.

I hope you will adopt the above, thank you!
