The United States is planning to put back North Korea to its state sponsors of terrorism after the latter was implicated in the Sony Pictures data breach in November.
North Korea is threatening to fight back against the U.S. in several forms, including cyber warfare, if the U.S. does not apologize for blaming them for the Sony hack.
According to the National Defense Commission for Pyongyang, the U.S. is wrong for blaming North Korea and that there were no grounds for their claim.
The Foreign Ministry of China said that there was not enough data to know if North Korea utilized Chinese facilities to conduct the hacking on Sony Pictures.
Hua Chunying, a spokesperson from the Chinese Ministry said that China opposes any form of cyber-attack, but would not point fingers if there are not "enough facts."
The U.S. government is discussing with China to aid in blocking cyber-attacks from North Korea.
U.S. President Barack Obama said that he does not consider the North Korea hack as an act of war, but a costly example of cyber vandalism.
Japan is also against the Sony hack. Yoshihide Suga, a Chief Cabinet Secretary, said that the country is keeping in touch with Washington regarding the issue.
Suga said that cyber-attacks are a threat to their country's national security.
The "Guardians of Peace" hackers leaked controversial emails and sensitive data from the Sony Breach. It threatened violence against those who would watch "The Interview" film, where the story revolves around killing the North Korean leader.
While North Korea is denying it was behind the cyber-attack, it lauded the hackers' efforts.
Sony has dropped the scheduled release of the film on Christmas day after major theaters backed out of showing the movie.
A report from the Policy Department of the National Defense Commission of North Korea stated that it has no information regarding the whereabouts of the hackers, and that it had proof that the U.S. government is behind the making of "The Interview."
North Korea already conducted a "counteraction," according to the department.
