Japan–South Korea relations
South Korea summons the Japanese ambassador following remarks by a Japanese senior official mocking South Korean President Moon Jae-in. Moon had hinted at a summit with Japanese Prime Minister Yoshihide Suga, to which the official responded that it was not a possibility and that Moon was "masturbating". South Korea states that the remarks were highly inappropriate, but the Government of Japan said that the remarks were not directed at Moon.
