Over the weekend, the United States asked China to help it stop North Korean hackers. Now, China has publicly stated that, while it condemns cyberattacks, it believes that there is no proof that North Korea was responsible for the recent hacks of Sony Pictures.
"[We have] reaffirmed China's relevant position [to U.S. Secretary of State John Kerry], emphasizing China opposes all forms of cyberattacks and cyber terrorism... Before making any conclusions there has to be a full (accounting of) the facts and foundation. China will handle it in accordance with relevant international and Chinese laws according to the facts."
China is North Korea's only major ally, and it's fair to say that the US-China relationship is uneasy, especially on matters of digital security. So it's hardly surprising that China is taking a cautious approach. The news will be disappointing for US officials, though, who on Saturday apparently explained to the New York Times:
"What we are looking for is a blocking action, something that would cripple their efforts to carry out attacks. [China's] cooperation would be critical, since virtually all of North Korea's telecommunications run through Chinese-operated networks."
