The offline business environment in China is also recovering. Luke Moffat, regional managing director of CBRE, a commercial real estate services firm scheduled to attend the expo, said their office occupier survey shows 71 percent of the respondents in China expect the business environment to improve or remain stable in the second half of the year.

He said shopping mall foot traffic in China has reached 80 percent of the pre-pandemic levels in May, and in prime properties the figure rose to above 90 percent.

As people going to offline stores are paying more attention to hygiene, Swiss third-party testing and inspection company SGS said they will showcase their service on hygiene control and management, which can evaluate a store's sanitation condition as fast as five minutes.

Smart vehicles are gaining momentum in China, as self-driving taxis are taking pilot runs this year in cities such as Beijing and Shanghai.

The CIIE bureau said it will set up an intelligent transportation sector in the automobile exhibition, and companies will display their new technologies and products such as vehicle sensors and control systems.
