BEIJING | By Michael Gavin (Barclays) | There are many reasons to be interested in the slowdown of the Chinese economy.

But China’s systemic significance is such that no economy is likely to remain utterly unscathed by a cyclical event there. The question is how scathed major economies will be, and the answer is of some considerable interest for investors, if only because they comprise such a large share of the world’s financial assets.
