A private jet linked to Tesla CEO Elon Musk landed in Beijing on Sunday, a flight-tracking app showed, as two people with knowledge of the matter said the billionaire was kicking off a surprise visit to the automaker’s second-biggest market.

Musk is seeking to meet senior Chinese officials in Beijing to discuss the rollout of Full-Self Driving (FSD) software in China and to obtain approval to transfer data collected in the country abroad to train algorithms for its autonomous driving technologies, one of the people said.

Tesla has since 2021 stored all data collected by its Chinese fleet in Shanghai as required by Chinese regulators and has not transferred any back to the United States.
