Most of the interest in the outcome of the Communist Party plenum in Beijing has focused on the economic decisions. But the Chinese government also announced that it plans to set up a National Security Council – which has obvious echoes of the White House decision-making apparatus.

The Chinese are not alone in making this move. Japan is also in the process of setting up a new National Security Council, which is meant to be operational by the end of the year. Some might find it a little ominous that at a time when Sino-Japanese tensions are so high, both countries are revamping their national security structures. But it could also be that the Chinese and Japanese are simply following foreign-policy fashion in the West. National Security Councils are all the rage. Britain set up an NSC in 2010, allowing the prime minister to chair regular meetings of all the senior ministers and officials dealing with security issues: foreign affairs, defence, intelligence and so on.

So what lies behind this proliferation of NSCs? In Britain’s case I have always suspected there is a case of White House envy. The Cameronites were all avid watchers of The West Wing – and I think rather enjoy the glamour of having their very own NSC.
