Mr Hansen said the seminar would also look at the need for manufacturers to take responsibility for the distribution channel.
"Value chains are shortening, and we have manufacturers going directly to retailers and to customers. There's now a dynamic relationship. The distributor provides a fundamental part of the value chain, but unless the manufacturers can help drive value and pull-through, then the whole circuit becomes constipated."

"We'll focus on areas such as what the exporter can do to negotiate points such as territory, pricing and performance criteria," she said.
