China has mooted the possibility of controlling the airspace over the disputed South China Sea, as it ratchets up rhetoric in response to a US overflight of an island claimed by China earlier this month.
A senior foreign ministry official spoke on Wednesday about the possibility of implementing an Air Defence Identification Zone over the sea, a move that would be widely regarded as an effort to stamp its sovereignty over a series of islands it claims. An ADIZ requires all aircraft flying through it to identify themselves to the controlling government.
“China has the right to establish ADIZs,” said Ouyang Yujing, director of boundaries and oceanic affairs for the foreign ministry, in an interview published in a Chinese newspaper.
