Chinese technology companies seeking to challenge the dominance of US companies including Amazon and Tesla have flooded Las Vegas, making up more than a quarter of those attending this year’s Consumer Electronics Show (CES).

Around 1,300 of the 4,500 show attendees are Chinese, according to data from the Consumer Technology Association which runs the show.

Some 500 companies alone, more than one tenth of the total in attendance, have the word “Shenzhen” in their name, hailing from the Chinese manufacturing metropolis where many western gadgets are manufactured.

Unfamiliar names from China aiming to woo attendees include Byton, an electric car start-up founded by former BMW and Apple employees.

Byton sought to raise its profile by making one of the first announcements at the show, unveiling its “truly smart” car on Sunday. The 4x4 includes facial recognition in a high-tech dashboard and says one charge of its car will be enough for a week of urban commuting.
