China says there will be "no room for negotiation" in its demand that U.S. airlines describe self-ruled Taiwan as part of China ahead of a deadline this week.

Foreign Ministry spokesman Geng Shuang said Tuesday that China hopes the U.S. government will urge businesses to follow China's requirements. He did not specify how China would punish defiant carriers, saying only that it will "wait and see."
