The Chinese ambassador said China still hopes that the two countries can maintain a "stable and healthy" relationship, but adding it requires corresponding efforts by the U.S. side.

"China itself cannot guarantee that the relations will move on the right tracks. It requires efforts by both side," he said.

China on Monday flatly rejected the U.S. indictment against five Chinese military officers on allegation of cyber theft, while announcing the decision to suspend activities of the China-U.S. Cyber Working Group.

Chinese Foreign Ministry spokesman Qin Gang denounced the U.S. accusation as "purely ungrounded and with ulterior purpose," warning that it jeopardizes China-U.S. cooperation and mutual trust..

The ministry also summoned U.S. Ambassador to China Max Baucus to lodge a protest with the U.S. side over the indictment and urge Washington to immediately correct its mistakes and withdraw the indictment.
