China's main stock got off to another bad start this week, continuing to sharp falls seen in the first week of trading in 2016.
The Shanghai Composite index fell 5.33% to 3,016.7 points on Monday.
Trading was suspended for a day on two separate occasions last week as a system designed to prevent volatility was kicked in when shares dropped in a single day.
However, regulators removed the system on Friday, which prompted somewhat of a fightback with shares growing 2% - although they were still 10% down on the start of the week.
Weak inflation figures also did little to boost investor confidence. Consumer inflation in China was 1.6% in December, up just 0.1 percentage point on November's result.
