Competition between Tesla and Chinese domestic rivals is intensifying as the U.S. firm continues to launch incentives to keep its cars attractive.

U.S. automaker Tesla's sales of China-made electric vehicles fell 11.5% to 63,238 units in January from a year earlier, data from the China Passenger Car Association showed on Friday. Deliveries of China-made Model 3 and Model Y vehicles were down 32.

The U.S. electric car company’s sales are sliding across Europe, amid what many see as interference in local affairs by Tesla’s chief executive, Elon Musk.
