Containment may have made sense to George Kennan in a world of two economically self-contained blocs. But it has no place in a system where China's involvement in the world capitalist economy is so pervasive and mutually beneficial. America would not only be shooting itself in the foot by adopting containment. Almost all of its allies and partners around the region, including Australia, would be doubling over in pain as well. And then there is the 'how' question. Even if someone was silly enough to promote containment as an idea, would it be doable? As New Zealand's Prime Minister John Key indicated in a recent talk on foreign policy, anyone who thinks China's impressive expansion can be reversed needs their head examined.
