China on Saturday accused the U.S. of committing a "serious military provocation" by flying an Air Force B-52 strategic bomber over a Chinese-controlled man-made island in the South China Sea.
China's Defense Ministry said in a statement that the U.S. is deliberately raising tensions in the disputed region where China has been aggressively asserting its claims to virtually all islands, reefs and their surrounding seas.
It demanded Washington immediately take measures to prevent such incidents and damage to relations between the two nations' militaries.
