German logistics firm HHLA on Thursday called on the German government to uphold its responsibility towards the port of Hamburg and finally approve an agreed investment by Chinese shipping firm Cosco. HHLA has been waiting for a final go-ahead from the economy ministry for 18 months and now expects to hear back soon, Chief Executive Angela Titzrath said. "We believe we have answered all the questions," she said at a presentation of HHLA's 2022 results.
