There was a similar aspect to China's retaliation against Japan's border controls. As the leader of a democratic country, Japanese Prime Minister Fumio Kishida had a responsibility to explain to the public why Japan was requiring stricter testing for travelers from China. On two occasions, Kishida publicly referred to the measures, before they were implemented on Jan. 8. But Beijing took these acts as hostile: By unnecessarily explaining the situation to the Japanese public, Kishida insulted Xi, who had just entered his third term, the thinking went. China's visa retaliation was likely hatched by China's new top-duo diplomats, Wang Yi and Qin Gang, out of maximum consideration to Xi. [...] A diplomatic source said that the two cannot afford to be seen as too soft on Japan from the get-go. "They had no choice but to take some countermeasure." If the visa ban had persisted over the long haul, economic relations between the countries, the world's second- and third-largest economies, would undoubtedly have collapsed.
