SAN FRANCISCO — Google has delayed the debut of two mobile phones designed to connect with its Internet services in China, widening the void that might be opened if the company and Beijing can't resolve their rift over online censorship and security.
The phones, made by Motorola and Samsung, use the Android operating system, created by Google to steer people to its search engine and other services. China Unicom Ltd. was supposed to be the carrier.
The postponement Tuesday is the latest aftershock from Google's threat to shut down its search engine and other services in China, which could cut off the world's most populous country from Google through any kind of computer or phone.
Google intends to maintain its China-based search engine only if the government relents on rules requiring the censorship of content the government considers subversive. The ultimatum came last week after Google said it uncovered a computer attack that tried to plunder its software coding and the e-mail accounts of human rights activists protesting Chinese policies.
Putting the sale of the Android-powered phones on hold is a logical extension of Google's threat. It doesn't make sense to sell the devices in a market where key services might be restricted or unavailable, said Forrester Research analyst Charles Golvin.
The absence of Google's services might discourage the development of other Android-equipped phones for China's market, limiting customer choices among a breed of mobile devices that are becoming increasingly popular in other parts of the world.
Some Android devices hit the market before Google took its stand on China. For instance, Samsung introduced an Android phone, the Galaxy, in China last year. That phone will remain on sale.
This month Google also began selling its own Android phone, the Nexus One. But that device so far is only available in the United States, United Kingdom, Singapore and Hong Kong. There's no indication when Google might sell it in China or elsewhere.
In a statement, Motorola said it remains committed to bringing "the power and promise" of Android phones to China. The manufacturer last month unveiled two Android devices, the MT710 and XT800, in China.
A Samsung spokeswoman in Korea had no immediate comment.
Keeping new Android phones off the China market would hurt Google, too. The company expects Android devices to become one of the main ways people get to Google's search engine, to its e-mail service and to Google-owned YouTube during the next decade.
China is already the world's largest mobile phone market, with more than 700 million accounts, and its rapidly growing economy is providing more people with the means to buy the latest gadgets.
"It's a high-stakes poker game for both sides," said Michael Grossi, director of Altman Vilandrie & Co., a telecommunications consultant.
The showdown hasn't hurt Google's stock much so far. It gained $7.62 Tuesday to close at $587.62, just $3 less than its value when Google publicly challenged China.
The tensions with Google could deprive China's people and businesses of other technology if major U.S. innovators and equipment makers decide to curtail or close their operations in the Asian country to protest the government's policies. So far, though, there has been little indication other big companies are willing to forgo a chance to cash in on the opportunities emerging in China.
Google remains optimistic it can persuade China's ruling party to loosen its restrictions on free expression on the Internet, giving the company the assurances it says it needs to keep doing business in the country. The outcome of those discussions appear likely to determine whether the Samsung Electronics Co. and Motorola Inc. phones will be sold in China.
China's government has given little indication it's willing to budge from its stance on censorship. The latest sign of intransigence came Tuesday, when a government official mentioned Google by name for the first time since the dustup began.
"Foreign enterprises in China need to adhere to China's laws and regulations, respect the interests of the general public and cultural traditions and shoulder corresponding responsibilities," Foreign Ministry spokesman Ma Zhaoxu said at a regular news briefing. "Google is no exception."
Ma said China strictly prohibits computer hacking in any form.
