The China market is the key to Tesla's global growth ambitions. In fact, Tesla's Model 3 sedan is one of the best-selling EVs in the country. The company has a dominant market share in the mainland with sale of 147,445 vehicles last year. The company's flagship model in China — Model Y — also secured green signal for sale in the country last December. The picture, nevertheless, seems to have changed recently. Tesla was called in by regulators in China over recalls, quality and safety concerns with its cars, including battery fires and abnormal acceleration.
