China Flags "Security Incidents" With Apple iPhones, But No Ban Yet

If Beijing goes ahead with an iPhone ban, the unprecedented blockade will be the culmination of a years-long effort to root out foreign technology use in sensitive environments.

China flagged security problems with iPhones while saying it isn't barring purchases, the government's first comments on the topic after news reports that authorities are moving to restrict the use of Apple Inc. products in sensitive departments and state-owned companies.

"We noticed that there have been many media reports about security incidents concerning Apple phones," Chinese Foreign Ministry spokeswoman Mao Ning said at a regular press briefing in Beijing, without elaborating.

China plans to expand a ban on the use of iPhones to a plethora of state-backed companies and agencies, Bloomberg News had reported earlier, a sign of growing challenges for Apple in its biggest foreign market and global production base. Several agencies have begun instructing staff not to bring their iPhones to work.
