We have been using Ali Datong for export since the opening of Ali International Station, which not only improves efficiency, but also reduces costs. However, Ali Chase has now been upgraded to Alibaba's cross-border supply chain. In addition to the services mentioned above, credit insurance, logistics, payment and settlement, finance, market procurement and other services have been added, which is more professional and comprehensive than before.
