China stocks reversed early gains to end lower on Tuesday, after data showed factory-gate inflation had cooled for a third straight month in September amid lean domestic demand, reflecting more pressure on the world's second-biggest economy. The blue-chip CSI300 index ended 0.8 weaker at 3,100.97 points, while the Shanghai Composite Index also closed 0.8 percent lower at 2,546.33 points.
Most sectors lost ground, led by real estate and material firms. China's factory-gate inflation cooled for a third straight month in September amid ebbing domestic demand, pointing to more pressure on the world's second-biggest economy as it remains locked in an intensifying trade war with the United States.
Adding to worries was an S&P Global Ratings report that said off-balance-sheet borrowings by Chinese local governments could be as high as 40 trillion yuan ($5.78 trillion) and amount to "a debt iceberg with titanic credit risks".
There were also worries over the increasing tension between Saudi Arabia and the West that have fanned geopolitical concerns.
