The head offices of all the leading import and export firms, mining companies, and banks, not only for Kenya but also for East Africa as a whole, are in one or the other of these two cities. Warehousing facilities are extensive in both cities. Retail outlets are generally small and are often owned and operated by a wholesaler.
