Well it is now official that South Korea has been removed from Japan’s so called “white list” of favored trading nations:

Prime Minister Lee Nak-yon on Saturday blasted Japan for its decision to remove South Korea from a whitelist of trusted trading partners, saying that it “crossed a line it should not have.”
“(The decision) is the second retaliation after the country imposed export restrictions on key chip materials,” Lee said at a Cabinet meeting.
He also said such moves could “jeopardize bilateral relations between South Korea and Japan, international free trade and interdependent economic cooperation regime, and cause a crack in the three-way security alliance with the United States.”
“We cannot but sternly deal with the matter.”
On Friday, Japan’s Cabinet passed a bill striking South Korea from its list of countries that require only minimal procedures to purchase sensitive materials that can be used for military use.
South Korean President Moon Jae-in has denounced Japan’s move as a “very reckless decision”, warning that South Korea will take corresponding measures and Japan will bear full responsibility for the consequences.

You can read more at the link, but what I find most interesting is that the Moon administration has a more stern response to Japan over a trade spat the ROK government created in the first place, than North Korea shooting off missiles the Kim regime states are meant to destroy Seoul.
So when is the Korean government going to show this level of anger at North Korea for not complying with their military agreements with South Korea?
