China warns U.S. surveillance plane

The Chinese navy issued warnings eight times as a U.S. surveillance plane on Wednesday swooped over islands that Beijing is using to extend its zone of influence.

The series of man-made islands and the massive Chinese military build-up on them have alarmed the Pentagon, which is carrying out the surveillance flights in order to make clear the U.S. does not recognize China's territorial claims. The militarized islands have also alarmed America's regional allies.

Former CIA Deputy Director Michael Morell told CNN's Erin Burnett Wednesday night that the confrontation indicates there is "absolutely" a risk of the U.S. and China going to war sometime in the future.

A CNN team was given exclusive access to join in the surveillance flights over the contested waters, which the Pentagon allowed for the first time in order to raise awareness about the challenge posed by the islands and the growing U.S. response.

CNN was aboard the P8-A Poseidon, America's most advanced surveillance and submarine-hunting aircraft, and quickly learned that the Chinese are themselves displeased by the U.S. pushback.

"This is the Chinese navy ... This is the Chinese navy ... Please go away ... to avoid misunderstanding," a voice in English crackled through the radio of the aircraft in which CNN was present.

This is the first time the Pentagon has declassified video of China's building activity and audio of Chinese challenges of a U.S. aircraft.

The aircraft flew at 15,000 feet in the air at its lowest point, but the U.S. is considering flying such surveillance missions even closer over the islands, as well as sailing U.S. warships within miles of them, as part of the new, more robust U.S. military posture in the area.

Soon after the Chinese communication was heard, its source appeared on the horizon seemingly out of nowhere: an island made by China some 600 miles from its coastline.

The South China Sea is the subject of numerous rival -- often messy -- territorial claims over an area that includes fertile fishing grounds and potentially rich reserves of undersea natural resources. China is increasingly showing that even far from its mainland, it sees itself as having jurisdiction over the body of water.

Wednesday's mission was specifically aimed at monitoring Chinese activities on three islands that months ago were reefs barely peaking above the waves. Now they are massive construction projects that the U.S. fears will soon be fully functioning military installations.
