If its European workers producing those cars, it doesn't really help the Chinese economy much though. China needs to move to higher value production in factories. Car production is such a product. China should be producing 30-40% of world's car in its factories once it reaches its full potential.
Chinese brands are also selling cars in Europe with a huge profit margin right now. They can probably still have the same price but swallow the tariff out of their profit margin. China needs to gain market share as quickly as possible and gain consumer recognition and trust. That will be the key battle.
Also, I think people are focusing too much on Electric Cars but ignoring China's massive quality improvement in Ice cars as well. They r gaining market share in many countries. They r just less known as a brand and probably lack the service/sales network. But the product is equally good.
Electricity is extremely expensive in Europe due to Russia sanctions. As long as oil remains cheap, Electric cars will likely remain a niche. China is unique because of its heavy focus on charging infrastracture. But I don't think Electric cars will see that level of adoption in the next 20-30 years in most countries. All the self-driving, touch screen stuff can be and will be easily implemented in Ice cars. That will take away the cool factor of electric cars. Then it will again be a decision about cost/benefit analysis of eletric car vs Ice car. And Electric car will lose that battle as long as oil remains cheap.
Ice car will be where China gains the big market share in my opinion. It will be the hidden dark horse that surprise people in a couple of years. Just like how Electric cars from China came into limelight only this year. Chinese Ice cars will also get into big limelight in the next few years.
