"Foolish and hopeless."
That is how Bloomberg is describing Japan's actions against South Korea.
In an editorial, it said Japanese Prime Minister Shinzo Abe is abusing trade policy by using it to resolve a political dispute.
It said Tokyo is clearly retaliating against South Korea for its top court rulings ordering Japanese firms to compensate the Korean victims of wartime forced labor.
Bloomberg added that, through the export curbs, Japanese suppliers will lose market share as well as their reputation for reliability and that Tokyo should make the first move in lifting the export controls.
