China demands end to US surveillance flights after dangerous intercept.

China has called on the US to stop its "dangerous acts of provocation" after a Chinese fighter jet intercepted an American spy plane over the South China Sea last week. The US accused the Chinese fighter pilot of conducting an "unnecessarily aggressive maneuver." The incident comes after China rejected a US request for a meeting between the defense chiefs from both nations. Both China and the US have seen relations plummet amid growing concerns that Beijing will invade Taiwan to reunify it with the Chinese mainland.
