A promising overseas enquiry is not the same thing as an export order. Between the two lies trade diplomacy: the patient, often unglamorous work of establishing confidence between people, companies and governments that do not automatically understand one another. It is where commercial judgement meets national interest, and where a useful introduction can either develop into years of business or disappear after the first polite exchange.
For much of my working life in international trade, that distinction mattered greatly. A manufacturer might possess a sound product, competitive engineering and the determination to export. Yet it could still fail abroad because it misread the local decision-making structure, relied on the wrong intermediary, or treated a government connection as a shortcut rather than the beginning of a relationship.
