First, the story is about a carrier than runs a route between the Hawaiian Islands, not between Hawaii and US  west coast. Second, you believe that a foreign shipper will charge you less to ship to/from Hawaii? Please explain how and why. Third, the reason freight rates are so cheap elsewhere is because there are too many ships trying to carry to little cargo. Freight rates are so low (shipowners losing money) that many shipowners are either in bankruptcy, already have collapsed and left the market, or are about to go out of business. That means they have left markets and abandoned their customers. Look up Hanjin shipping for an idea of what happened to those people who had cargo stuck onboard their ships that were seized in ports. It never ceases to amaze me people ask for something they know so little about. Getting foreign carriers to run Hawaii's trade and push out US Flag carriers is not a good long term answer to your perceived problem.
