General Motors will begin using a high-tech electric vehicle platform developed in China for the Cadillac Optiq.

The automaker hasn't said which markets this will be available in, but the U.S. remains unlikely.

Chinese hardware and software face heavy restrictions in the U.S.

The next version of the Cadillac Optiq will swap General Motors’ U.S.-designed electric vehicle architecture for a platform developed through a joint venture in China, Reuters reported on Wednesday, citing a person familiar with the plans.

While this platform is unlikely to make its way to the U.S. due to restrictions on Chinese hardware and software, it’s a sign of Western automakers increasingly tapping advanced Chinese technology to stay relevant in the global EV market. The Reuters story did not specify where the Optiq using Chinese EV technology would be sold.
