There is nothing particularly ironic about that - it's in the Chinese government's interest to control its own citizens and subvert its adversaries' control over theirs, and vice versa. See also Russia granting asylum to Snowden, and the myriads of Chinese, Russian, Middle Eastern etc. dissidents sheltered by the Western bloc. I imagine we would see more of the converse were it not for the language barrier, too. If anything, we should be grateful for this situation; in a worse world all these governments would abide by gentlemen's agreements to not act against each other when it comes to controlling their subjects, notwithstanding their differences.
