 The United States sent nuclear-capable bombers, accompanied by Japanese fighter jets over the Sea of Japan in the first military show of force by the two allies since a bitter feud erupted between Japan and China last month.

The drills included two U.S. B-52 strategic bombers and six Japanese F-35 and F-15 fighter jets, according to the Japanese Defense Ministry's Joint Staff.

"This bilateral exercise reaffirms the strong will between Japan and U.S. not to tolerate unilateral changes to the status quo by force," Japan's Joint Staff said in a statement — language that Japan often uses to refer to the status of Taiwan, a self-governed island that China claims as part of its territory.

This follows joint drills by Chinese and Russian strategic bombers and fighters on Tuesday that prompted Japan and South Korea to scramble planes to monitor them. South Korea lodged a diplomatic protest over the incident.
