China has struggled for five years to ensure the exchange rate does not fall too far below seven yuan per US dollar, but the currency has gained about 7 per cent against the US dollar in the past six months
, stoking debate among Chinese economists over whether authorities should intervene to slow the rally.

But that has not stopped speculation that Beijing is searching for a new comfort zone for the yuan’s value.
