SHANGHAI - The working model of Tesla Gigafactory Shanghai has benefited both China and the United States, said Gavin Newsom, governor of the US state of California, during his visit to the factory on Sunday.

The advantages here are self-evident, not only in terms of the supply chains but also the technology in terms of improving quality constantly, said Gavin Newsom, governor of the US state of California

Newsom test-drove the upgraded Model 3, which was manufactured at Gigafactory Shanghai and has supplied multiple markets in the Asia-Pacific and Europe.

Newsom expressed appreciation for the China-US cooperation model, noting that "during the day, the engineers (in Shanghai) are working on the new models, while during the evening, they shift over and transfer to the United States because they are awake. So this rotation, 24/7 collaborative spirit, back and forth, is healthy."
