Multiple outlets report that the Wall Street Journal says some Tesla executives are being asked to prepare for a possible separation of the company’s China business. The reported goal is to reduce geopolitical and regulatory complications if Tesla were to pursue a merger or other combination with SpaceX, which is closely tied to U.S. national security and export-control obligations.

According to the accounts, Tesla is evaluating several restructuring paths, including an outright sale, a spin-off, or winding down the China unit. The WSJ report also describes internal efforts to increase separation between Tesla’s U.S. and China operations, including creating a more independent China-focused sales structure for exports and establishing stricter internal controls limiting cross-access by China-based employees.

The reports point to the regulatory challenge of combining a major U.S. defense contractor with manufacturing and technology assets located in China. They also cite concerns that Chinese regulators may be reluctant to allow a company with U.S. defense contractor ties to oversee operations, data, and technology in China.

Elon Musk and Tesla’s China team deny the report, with Musk calling it “absurdly fake news.”
