Business-to-business eCommerce holds much stronger short and medium term potential for China than business-to-consumer. Business-to-business transactions are still small compared with the United States, Europe and even some Asian countries, but traditional business - such as petroleum, textiles and automobiles - can capture very significant cost savings and efficiencies through developments of vertical and horizontal portals similar to those now springing up around the world. Portals such as YourImporter, e-Markterplace and ChinaMallUSA are establishing the models for the future.
