This happed in April? Then by CNN reported. I think, it was exercises by US? NOTE MY QUESTION MARKS. I don't know.

Perhaps most interesting about Friday's encounter is that it was all recorded by a CNN reporter and camera crew who were aboard the Navy flight.
CNN reports:
Aboard a US Navy P-8A Poseidon reconnaissance plane, CNN got a view from 16,500 feet of low-lying coral reefs turned into garrisons with five-story buildings, large radar installations, power plants and runways sturdy enough to carry large military aircraft.
During the flight the crew received six separate warnings from the Chinese military, telling them they were inside Chinese territory and urging them to leave.
