SHANGHAI: Chinese stock markets plunged to their lowest levels in four years on Thursday (Oct 11) following a global rout.
The benchmark Shanghai Composite Index dropped 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, the lowest point since September 2014.
It is the second dive in Chinese bourses this week after both Shanghai and Shenzhen fell nearly four per cent on Monday.
"(The) 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."
Other Asian markets also tumbled Thursday following the worst session on Wall Street for months, as US President Donald Trump said the Federal Reserve had "gone crazy" with plans for higher interest rates.
"With the global markets rout, mainland shares cannot stay safe," Guangzhou Wanlong Securities said in a research note.
"Interest rate put aside, the Sino-US trade spat is to blame for the October market rout because people are worried the friction would evolve into a political confrontation."
Tokyo and Hong Kong both shed around four per cent, while Taipei was down around six per cent. Seoul fell more than four per cent and Sydney and Singapore both dropped more than 2.5 per cent.

Trump told reporters that he thought that "the Fed is making a mistake" as he arrived for a campaign rally ahead of the US mid-term elections.
Trump has repeatedly touted Wall Street records as proof of the success of his economic programme. But he downplayed the first major drop in months, saying it was a "correction that we've been waiting for".
But International Monetary Fund chief Christine Lagarde hit back on Thursday, defending rate hikes that she said were justified by fundamentals.
"It is clearly a necessary development for those economies that are showing much improved growth, inflation that is picking up... unemployment that is extremely low," she told reporters in Bali where the Fund is meeting.
The rout in US shares followed substantial losses on European bourses, due in part to tensions between Brussels and Rome over Italian budget plans that have revived fears about the eurozone.
Bourses in Paris and Frankfurt both lost more than two per cent, while London fell 1.3 per cent.
"It's just a beginning," CEB International research head Banny Lam told Bloomberg.
"The US tech bubble may take a while to burst and we are facing many external uncertainties - trade wars, risks in emerging markets currencies and oil price."
Many of the biggest US names fell hard in Wednesday's session, with Apple, Boeing and Facebook all slumping more than four per cent and Amazon, Nike and Microsoft shedding more than five per cent.
Stocks have been under pressure since the yield on 10-year US Treasury bonds jumped above three per cent last week, a sudden move that raised fears of an overheating economy, speeding inflation and more aggressive Federal Reserve rate hikes.
In Hong Kong - where the benchmark Hang Seng index is already down 15 per cent this year - some of the biggest listed companies were also under pressure.
Chinese internet group Tencent fell for the tenth consecutive day, dropping more than seven per cent through morning trade.
China Mobile shares fell 3.7 per cent, insurance group Ping An dropped 4.1 per cent and China Construction Bank lodged a slide of 3.2 per cent.
The turmoil on stock markets came after the International Monetary Fund slashed its global growth forecast Monday on worries over the US-China trade war and weakness in emerging markets.
In other markets, oil extended declines in Asian trade Thursday following a sharp build in US crude inventories and fears Hurricane Michael would hurt demand.
