> Both actions are perfectly reasonably justified by self-interest

If that's a justification then isn't every kind of hypocrisy justified by self-interest?

Hypocrisy is characterized (to my mind) by criticism of the actions of others that one undertakes oneself, with a presumed unawareness that the conflict exists.

The Chinese government is not acting with any sort of denial; these two actions may hold others to standards that they don't follow, but they don't seem to be avoiding that fact.

All nations look out for their self-interest first and foremost over any concerns of hypocrisy. The US is a prime example.
