A Chinese fighter jet came within about 150 feet of a Japanese naval reconnaissance plane over the weekend, the Japanese Defense Ministry said Thursday, an action the US ambassador to Tokyo called “dangerous” and “reckless.

The maneuvers over international waters in the Pacific last weekend prompted Japanese officials to warn China not to repeat them and risk a collision.

Japan's Defense Ministry said Wednesday a Chinese J-15 fighter jet's "abnormal approaches" brought it within 49 yards of Maritime Self-Defense Force P-3C surveillance planes over the past weekend.
