China invests in Germany? What are you talking about. The economic relationship between China and Germany is not an investment relationship, and Germany is not a country like Greece.
In 2020, the total trade volume between China and Germany exceeded US $212.1 billion, China is the largest importer and exporter of Germany. Germany is China's trade deficit country, only two of China's deficit countries are industrial countries, and the others are ore selling countries. So the relationship between China and Germany is not investment, but cooperation. The two countries have in-depth cooperation in environmental protection technology, renewable energy, new energy vehicles, robotics and automation, industry 4.0, artificial intelligence, aerospace technology, biomedicine and other industries.
It is impossible for both countries to give up those. Of course, I don't think the Greeks to understand this.
