"Western governments have pointed the finger of blame for targeted Trojan attacks towards China, which has denied any involvement in the assaults."
Can you imagine the processing a Westerner would need to do, to effectively target the Chinese with a sophisticated, stealthy phish? How perfect do you think their Mandarin would be? Which does make it difficult to believe, beyond a shadow of reasonable doubt, their ultimate responsibility, even should there be some involvement.
Probably they'd have to outsource the work to a Westerner ...although it could also be a crazy self-harm type act to throw suspicion upon them, as they surge ahead in their development, unhindered by the Western/foreign language honey trap sites.
Would that render them, or their leaderships, as being more intelligent/worldly wise/aware/progressive?
