Rarely has a deal encountered such strong government opposition. Six German ministries came out last month against Chinese shipper Cosco’s planned acquisition of a stake in a Hamburg container terminal. But it went through anyway.

The man who ensured its safe passage through the German cabinet was Chancellor Olaf Scholz. He insisted on a compromise — Cosco would have to make do with a 25 per cent stake, rather than the 35 per cent that was initially proposed.

But the German foreign ministry remained opposed, even after Scholz pushed it through. State secretary Susanne Baumann wrote an angry letter to Scholz’s chief of staff, Wolfgang Schmidt, saying the transaction “disproportionately increases China’s strategic influence over German and European transport infrastructure and Germany’s dependence on China”.
