Apple Inc. has come out swinging in its pitched battle with the government on its home turf.

But when it comes to its second-largest market, China, the Cupertino, Calif., company has been far more accommodating.

Since the iPhone was officially introduced in China seven years ago, Apple has overcome a national security backlash there and has censored apps that wouldn't pass muster with Chinese authorities. It has moved local user data onto servers operated by the state-owned China Telecom and submits to security audits by Chinese authorities.

The approach contrasts with Apple's defiant stance against the FBI, which is heaping pressure on the company to decrypt an iPhone that belonged to San Bernardino shooter Syed Rizwan Farook.
