BEIJING — Google today postponed the planned launch of its mobile phone in China amid a dispute with the government over Internet censorship and e-mail hacking the search giant said might force it to leave the country.

"It is postponed," Google spokeswoman Marsha Wang said. She said a launch ceremony planned for Wednesday was canceled but declined to give a reason for the decision or to say when the launch might be rescheduled.

Also today, a Foreign Ministry spokesman said the search giant must obey China's laws and traditions, suggesting the government was giving no ground in talks over Internet censorship and Google's threat to pull out of the country.

It was the government's first direct comment on Google since the U.S. company said Jan. 12 it would no longer censor search results in China and might shut down its China-based site Google.cn. The announcement prompted an outpouring of support from Chinese Web surfers.
