If you’re Japanese which is closer? Alaska or Kuwait?
Why does that matter to the seller in Valdez?
If you are a West Coast Refinery, which is closer? Alaska or Kuwait?
Much greater distances involved for West Coast.
Also, the links at post #17 show California and Washington State receiving the oil, as well as the oil not being exported from the West Coast.
