Team work I am not privileged to any information but if I had to speculate:
To execute and manage this end to end supply chain on multiple products and multiple Customers, they will need to set-up an effecient transactional business model between Korean suppliers and the different Customers. The objective should be to manage the business transactions without having to touch and own the products in transit. Based on their past projects and expertises, Graph would potentially be a good asset to set-up this business model and therefore they need to start talking to suppliers to establish the communication network.
