Japan is an ally of the US and the American reaction came quickly. "The policy announced by the Chinese over the weekend is unnecessarily inflammatory," White House spokesman Josh Earnest told reporters. To be more clear, probably, two unarmed U.S. B-52 bombers on a training mission flew over disputed islands in the East China Sea on Monday night EST without informing Beijing. "We have conducted operations in the area of the Senkakus. We have continued to follow our normal procedures, which include not filing flight plans, not radioing ahead and not registering our frequencies," spokesman Colonel Steve Warren said. The U.S. military aircraft were neither observed nor contacted by the Chinese aircraft. Japan's two biggest airlines – Japan Airlines and ANA Holdings – will stop providing flight information on Wednesday.
The international community manifests preoccupation. The UN Secretary General Ban Ki-moon called on Tuesday China and Japan to negotiate an end to their dispute. France and Germany each expressed their concern and urged restraint on all sides and Australia asked to Beijing's ambassador to express its opposition.
