BEIJING – Would China ever be willing to host an international policy discussion about the conditions that would legitimize invading another country to stop genocide or other mass-atrocity crimes from being committed within its borders? Given China’s long history of antagonism to “interference in internal affairs” in general, and to “humanitarian intervention” in particular, and in view of its contribution to the UN Security Council’s long paralysis over much less coercive measures in Syria, you would be in good company if you answered, “No.”
