WASHINGTON — The State Department is advising U.S. air carriers abroad to comply with China's demand that it be told of any flights passing through its new maritime air defense zone over the East China Sea.
Last week China declared that all aircraft entering the zone must notify Chinese authorities beforehand, and warned that it would take unspecified defensive measures against those that don't comply.
Some neighboring countries and the U.S. have said they will not honor the new zone and that it unnecessarily raises tensions.
State Department spokeswoman Jen Psaki said in a statement Friday that the U.S. remains deeply concerned about China's declared air identification zone. But Psaki says that it is advising U.S. air carriers abroad to comply with notification requirements issued by China.
