SHANGHAI, Oct 9 (Reuters) - China stocks fell on Monday as trading resumed following a long holiday as mixed holiday tourism data failed to convince investors of a strong economic recovery, while overseas uncertainties also curbed sentiment.

** The blue-chip CSI 300 Index lost 0.6% and the Shanghai Composite Index declined 0.7% by the midday recess.

** Meanwhile, the Hong Kong stock exchange delayed trading in both the securities and derivatives markets on Monday morning due to Typhoon Koinu.

** Chinese holidaymakers' spending surged during this year's eight-day Golden Week holiday, beating pre-pandemic levels but still falling short of government estimates.

** "The National Day golden week tourism data, together with the still above-50 September services PMIs, suggest the services recovery has decelerated but continues," said Goldman Sachs analysts in a note.

** "We believe additional policy easing will be necessary for further recovery in consumption and services, especially given the continued property downturn and still-dampened confidence."

** Overseas, U.S. stock futures slid in Asia on Monday as the military conflict in the Middle East boosted oil and Treasuries, while the sizzling September U.S. jobs report raised the rate stakes for inflation figures later in the week.

** In China markets, shares in tourism-related companies slumped 4.6% to lead the decline, while real estate developers plunged 2.3%.

** Agriculture shares dropped 1%, with pig-breeders Muyuan Foods, New Hope Liuhe down 6% and 3.3%, respectively. Physical hog prices declined during last week's National Day holiday due to rising supply and weak demand.

** In contrast, shares in automobiles rose 2.5%.

** Citigroup and J.P.Morgan raised their forecasts for China's annual growth last week, citing stabilizing economic indicators and Beijing's recent supportive policy measures.
