Shanghai Stock Exchange

Shares in China suffered another significant fall on Tuesday despite attempts made by the central bank to boost investor confidence.

The Shanghai Composite index dropped 6.42% at 2,749.79, with the Hang Seng index falling 2.4% to 18,879.44.

Investors grew more pessimistic as oil prices nearly wiped out the gains made on Friday. Brent crude oil fell 6.3% to $30.15 a barrel, having made a surprise increase of around 10% at the end of last week. Also, Iraq reported that its production of oil rose to record levels in 2015 - intensifying concerns of oversupply in the market.

China's central bank injected more liquidity to the Shanghai market, but it failed to boost confidence.

Wall Street also lost its gains made over the past two days, and Japan's Nikkei 225 fell 2.4%.
