Americans face a possible terrorist threat in China, according to information received by the U.S. government, FOX News has learned.

The unconfirmed information says U.S. interests in Beijing, Shanghai and Guangzhou face the threat, and that risks also exist against Americans in other cities' restaurants, churches and schools.

The State Department issued an official message after information was received that American citizens could be in danger.

"The embassy is looking further into the threat," said Sean McCormack, a spokesman for the State Department. "My understanding is it was a generalized threat against American interests, but especially in those three cities."

Americans are advised to be aware of their surroundings and be alert to possible threats.

"It doesn't talk about people canceling travel or leaving. But it really counsels increased awareness in certain places, I think, in Beijing, Guangzhou and Shanghai," McCormack said.

Visitors to China are encouraged register with the U.S. Embassy or U.S. Consulate through the State Department's travel registration Web site. The registration will give the government information about an upcoming visit to better assist in an emergency.
