German magazine Der Spiegel has published several NSA documents that Edward Snowden leaked, suggesting Chinese hackers stole documents about the F-35 Lightning II program.
A spokesperson for the Chinese Foreign Ministry called the accusations "baseless" in a press conference Monday, saying China is willing to work with all countries to ensure cybersecurity.
Although reports of hacks on the F-35 program go back to 2007, the documents published Saturday specifically label China as the culprit.
The documents also note more than 500 "significant intrusions" into the Department of Defense's systems, despite officials in 2009 denying that any sensitive information had been stolen. (Video via CBS)

Although the documents Der Spiegel published cover a wide range of cybersecurity topics, the documents relating to the F-35 are particularly notable, given China's recent advancements in the field of aeronautics.
A senior fighter pilot told the U.S. Naval Institute News the J-31 could soon be on par with the F-35, adding, "They should be because industrial espionage is alive and well."

U.S. officials have yet to comment on the published documents.
