Elon Musk's no.2 at Tesla goes back to China as the CEO isolates himself at the top

Elon Musk's key executive at Tesla, Tom Zhu, is returning to oversee operations in China after briefly expanding his role to include North American sales and overall leadership of Tesla's automotive business. Zhu's shift back to China follows a period where he was effectively second in command to Musk, who has recently reclaimed some of those responsibilities. This move comes amidst a series of layoffs and executive departures, suggesting a consolidation of power by Musk at Tesla.
