北京（路透社）——中国周一称其窃取F-35隐形战机项目的指控是毫无根据的，之前，一份德国杂志出版了斯诺登所披露的有关网络袭击的文件。
BEIJING (Reuters) - China dismissed accusations it stole F-35 stealth fighter plans as groundless on Monday, afterdocuments leaked by former U.S. intelligence contractor Edward Snowden on acyber attack were published by a German magazine.
五角大楼此前称黑客曾将国防项目的机密数据作为袭击目标，比如F-35战机项目，但并没有公开谴责是中国干的。
The Pentagon has previously acknowledged that hackers had targeted sensitive data for defence programmes such as theF-35 Joint Strike Fighter, but stopped short of publicly blaming China for theF-35 breach.
防卫专家称中国国产的隐形战机在设计上与F-35相似。
Defence experts say that China's home-grown stealth jets had design elements resembling the F-35.
五角大楼和洛克希德马丁公司称在那次的网络袭击中没有机密信息被窃取。
The Pentagon and the jet's builder,Lockheed Martin Corp, had said no classified information was taken during the cyber intrusion.
德国《明镜周刊》周六出版了斯诺登的一些文件，其中就包括了一份最高机密的美国政府文件，文件中称中国窃取了几兆兆字节的F-35项目数据，包括雷达设计和引擎图表。
German magazine Der Spiegel on Saturday published a cache of Snowden documents, including a top secret U.S. government presentation that said China stole "many terabytes" of data on theF-35 programme, including radar designs and engine schematics.
“这些用来对中国发起无端指责的所谓证据根本就是不正当的，”外交部发言人洪磊对记者说。
"The so-called evidence that has been used to launch groundless accusations against China is completely unjustified," Foreign Ministry spokesman Hong Lei told reporters.
他说网络袭击的“复杂本质”使得要想找到真正的袭击者变得非常困难，并称中国想和其他国家一起合作来防止黑客行为。
Hong said the "complex nature" of cyber attacks makes it difficult to pinpoint the relevant attacker, adding that China wanted to work with other countries to prevent hacking.
他说：“根据这位相关人士披露的资料，某些国家自己在网络安全中也有不光彩的记录。”
"According to the materials presented by the relevant person, some countries themselves have disgraceful records on cyber security," Hong added.
