China said on Monday it opposed all forms of cyberattacks but there was no proof that North Korea was responsible for the hacking of Sony Pictures, as the United States has said.
North Korea has denied it was to blame and has vowed to hit back against any US retaliation, threatening the White House and the Pentagon. The hackers said they were incensed by a Sony comedy about a fictional assassination of North Korean leader Kim Jong Un, which the studio has pulled.
China made no reference to calls by the United States for joint action with it and other countries to counter any similar cyberattacks.
“Before making any conclusions there has to be a full (accounting of) the facts and foundation,” foreign ministry spokeswoman Hua Chunying said. “China will handle it in accordance with relevant international and Chinese laws according to the facts.”
She said Chinese Foreign Minister Wang Yi “reaffirmed China’s relevant position, emphasising China opposes all forms of cyberattacks and cyber terrorism” in a conversation with U.S. Secretary of State John Kerry on Sunday.
China is North Korea’s only major ally, and would be central to any US efforts to crack down on the isolated state. But the United States has also accused China of cyber spying in the past and a U.S. official has said the attack on Sony could have used Chinese servers to mask its origin.
South Korea, which is still technically at war with North Korea, said computer systems at its nuclear plant operator had been hacked and non-critical data stolen, but there was no risk to nuclear installations or reactors.
“It’s our judgment that the control system itself is designed in such a way and there is no risk whatsoever,” Chung Yang-ho, deputy energy minister, told Reuters by telephone.
He made no mention of North Korea and could not verify messages posted by a Twitter user claiming responsibility for the attacks and demanding the shutdown of three ageing nuclear reactors by Thursday.
