Private companies are mostly profit-driven. State-owned companies are mostly policy driven. For example, cell phone companies make no profit by expanding their network to remote rural areas, yet they do. So state-owned companies are unlikely to cheat the public. In other words, state-owned companies are more trustworthy.
When Wuhan was locked down in 2020 because of COVID, airlines to Wuhan stopped. All the air fairs return to customers without any condition. In the west, however, customers have to go through many hassles to get their money back due to COVID interruption because the airlines in the west are private.
In the present shared laws in business, when there is a conflict between companies and their customers, the law mostly sides with the companies when the companies are private and side with the customers when the companies are state-owned. This makes sense. State-owned companies are in the interest of the people, customers included. Both sides feel reasonable because they are all on one side, the state.
China is the People’s Republic of China. The state is of the people, by the people, and for the people.
