BEIJING: China's factory activity unexpectedly slipped into contraction in July, pressured by shrinking new orders that reinforced concerns over slowing economic growth, weak demand at home and elevated production costs.The official manufacturing purchasing managers' index (PMI) fell to 49.2 from 50.3 in June, below the 50-mark separating growth from contraction and hitting a 5-month low, according to a survey by the National Bureau of Statistics. It missed the median forecast for 50 in a Reuters poll.The non-manufacturing PMI, which includes services and construction, also contracted, declining to 49 from 50.2 in June. The composite PMI came in at 49.3 compared with a 50.6 reading the previous month. The grim readings underscore the headwinds confronting the economy, with growth already slowing in the second quarter despite solid external demand.Show MoreShow LessChina's Q2 economic growth cools to 3.5-year low as imbalances worsenChina's top leaders set to hold October meeting on internal governance, pledge measures to support economyGross domestic product growth in the second quarter slowed to 4.3 per cent from 5.0 per cent in the first three months, below the official annual target of 4.5 per cent to 5 per cent, adding pressure on policymakers to deliver stronger stimulus measures to shore up domestic demand and investment.PMI data released by the NBS showed that demand dropped sharply, with the subindex for new orders sinking to 48.5 from 51.2 the previous month.
