Reuters reports China on Thursday urged the United States to cut back on, or even stop, its close surveillance of the Asian giant using patrol aircraft, if it seriously seeks to repair damaged bilateral ties. Ties between the world's two largest economies have been strained by competing territorial claims between China and its neighbors, some of them U.S. allies, in the South China and East China seas. The two countries have exchanged barbs over a jet intercept of a U.S. navy patrol plane by a Chinese aircraft last week, with the United States saying the Chinese jet came within 10 m. (33 ft) of its plane over the sea. China has said the criticism by the United States, which filed a diplomatic complaint with Beijing on Friday, is groundless and that its pilot kept a safe distance. Military officials from both countries held talks on rules of behavior this week at the Pentagon, a U.S. official said.
