Mercedes boss Ola Källenius calls for lower tariffs in the EU. European car manufacturers have been important players on the global market for decades.

But with the increasing focus on electric cars, manufacturers from China are gaining market share. The EU Commission accuses the Chinese leadership of giving advantages to local manufacturers with illegal subsidies. Mercedes doesn't just rely on China for sales. About 20 percent of the company's shares belong to the Chinese car manufacturers Geely and BAIC. Most German models sold in China are produced there.
