Chinese stock markets plunged to their lowest levels in four years on Thursday following a global rout, with shares in around 1,000 firms falling to their daily limit of 10 per cent.
Shanghai fell 5.22 per cent, or 142.38 points, to 2,583.46, marking the lowest level since November 2014.
The Shenzhen Composite Index, which tracks stocks on China's second exchange, plummeted 6.45 per cent, or 89.15 points, to 1,293.90 -- its lowest point since September 2014.
"Chinese market already suffered a blow in confidence after Monday and investors were in a very sensitive state of mind," said Zhang Yanbing, analyst with Zheshang Securities.
"So they panicked and overacted today."
It is the second plunge this week for the Chinese mainland market after both Shanghai and Shenzhen saw a drop of nearly four per cent on Monday.
Other Asian markets also plunged Thursday following the worst session on Wall Street for months after US President Donald Trump said the Federal Reserve had "gone crazy" with plans for higher interest rates.
