The two countries had been in talks about holding a top-level encounter during the Games to improve relations that have plunged to their worst level in years over historical disputes.

But things went sour after a Japanese diplomat at the embassy in Seoul reportedly likened the South Korean president’s efforts to pleasuring himself.

“President Moon is masturbating himself,” Soma told a reporter at a South Korean cable news station Friday, according to The UK Times.

“Japan does not have the time to care so much about the relationship between the two countries as South Korea thinks.”
