China Thursday upped the stakes in the China-America hacking blame game by accusing the United States of launching hack attacks against Chinese government networks. According to the China's defense ministry, Chinese military systems were subjected to 144,000 attacks per month throughout 2012, and 63% of those attacks came from the United States.

"The Defense Ministry and China Military Online websites have faced a serious threat from hacking attacks since they were established, and the number of hacks has risen steadily in recent years," said ministry spokesman Geng Yansheng, Reuters reported. Geng's comments were delivered in a monthly press briefing that's closed to foreign reporters, and which were later distributed by the government.
