No judgment yet on Sony; evidence awaited

As Washington continues to lobby China to put more pressure on Pyongyang, Beijing clearly stated its opposition to any form of cyberattack but has yet to make a final judgment regarding the hacking of US-based Sony Pictures Entertainment.

There may be a number of possible technical explanations behind the attack, experts said, and it is still too early for Beijing to form any conclusion before Washington provides tangible evidence.

US Secretary of State John Kerry briefed Foreign Minister Wang Yi on Washington's viewpoints about the cyberattack in a telephone conversation on Sunday.
