A bit obvious
First off, it's laughable to report this as something serious and scary as "commie hackers penetrate our systems OMGG!!" All businesses and government departments receive unknown attacks everyday, just block and move on.
Secondly, why on earth would they use the method of spamming/phishing for passwords? It's too obvious, and something I would expect Nigerian and other part time hackers from other countries to do for the money.
Lastly, there is no guarantee it is the Chinese government's actions, or even the people involved whose computers are affected. How many of our computers (obviously not us, we're geeks and too good for that... right?) in Britain and America are open to act as a bot due to zero security...we don't call it the actions of the UK government do we? Due to the number of lax security PCs in China, and the country being an easy scapegoat, criminals and other nefarious organisations would use it as a good way to shield their own activities...I wouldn't be surprised if American hackers (state sponsored?) are taking control of computers in China and using it to hack countries around the world that only China would e.g. Tibet, America, separatists etc... it would suit the US agenda well, because they are pushing Congress to pass increased budgets for their cyberwarfare activities.
