South Korea, Japan Butt Heads Over Coronavirus Prevention Kelly Kasulis SEOUL - After months of cooling tensions, Japan and South Korea may be on the verge of another row, this time, over the COVID-19 coronavirus outbreak. South Korea sent out a foreboding omen Friday after Japan said it would quarantine travelers from South Korea or China. South Korea's National Security Council called the decision "unreasonable, excessive and extremely regrettable," adding it would consider reciprocal measures. South Korea now has the second-largest outbreak in the world, with at least 6,767 confirmed cases of COVID-19 and 45 deaths as of mid-afternoon Saturday. Meanwhile, Japan has more than 1,000 cases between its mainland and the Princess Diamond cruise ship. The nations, however, have taken different approaches in handling their outbreaks -- South Korea has tested its citizens for COVID-19 aggressively compared to Japan, using thousands of kits more per day. In Japan, chief government spokesman Yoshihide Suga called the travel curbs decision "result of a comprehensive review of the information available about the situation in other countries and the effects of other measures." Although several other nations have banned the entry of South Korean travelers, Japan's move likely hit a nerve with Seoul because of already-existing, unresolved conflicts between the two countries. .
