China’s End of Exuberance

MILAN – China’s growth has slowed considerably since 2010, and it may slow even more – a prospect that is rattling investors and markets well beyond China’s borders. With many of the global economy’s traditional growth engines – like the United States – stuck in low gear, China’s performance has become increasingly important.

But now growth rates for Chinese exports and related indices in manufacturing have fallen, largely owing to weak external demand, especially in Europe. And the Chinese authorities are now scaling back the other major driver of their country’s growth, public-sector investment, as low-return projects seem to generate aggregate demand but prove unsustainable fairly quickly.
