The figures could result in a revision of the a 0.1% annualised contraction in gross domestic product (GDP) during the quarter, which was initially calculated before these figures were available and were based on projections of a widening trade gap.
"The economy did not fare as badly as the initial GDP estimate suggested in the fourth quarter," said Chris Williamson, chief economist at financial information firm Markit.
"The data also add to an increasingly bright picture of the global economy at the turn of the year."

That fact rankles with American manufacturers who believe the Chinese benefit from an unfairly weak currency.
