TOKYO (Reuters) - Asian shares retreated to two-year lows on Wednesday after Chinese stocks extended their plunge, continuing to stoke fears about the stability of China's economy.
With Chinese stocks steepening their decline, spreadbetters forecast a lower open from Britain's FTSE (FTSE), Germany's DAX (GDAXI) and France's CAC (FCHI).
The Shanghai Composite Index (SSEC) retreated 2.8 percent, extending Tuesday's 6 percent slide, amid growing worries that the government could be scaling back its rescue efforts. [.SS]
"Market confidence was hit the most by signs that the 'national team' is starting to retreat," Zhou Lin, analyst at Huatai Securities said, referring to government funds that bought stocks in early summer to halt a market rout.
China's securities regulator said late last week that the market had normalised and the government would allow market forces to play a bigger role in determining stock prices.
Japan's Nikkei (N225) fell 1.5 percent and South Korea's Kospi (KS11) lost 1.3 percent.

MSCI's broadest index of Asia-Pacific shares outside Japan (MIAPJ0000PUS) slid to a two-year low and was last down 0.3 percent. Australian stocks (AXJO) bucked the trend and climbed 1.3 percent.
The yuan, which tanked last week after China's shock devaluation but has shown signs of stabilising after Beijing later worked to arrest its fall, has begun to feel the tremors from sliding Chinese equities.

"We think yesterday's stock market crash (in China) reinforced yuan depreciation sentiment, which will encourage more capital outflows, necessitating more open market operations and ultimately a reserve requirement ratio cut in the current quarter," strategists at ING wrote.
The spectre of a slowdown in China's economic growth and a U.S. interest rate hike have hit asset markets in emerging economies hardest.
MSCI's emerging market index (MSCIEF) fell to its lowest level since October 2011. It has dropped more than 20 percent from the year's peak hit in April.

A number of emerging market currencies, meanwhile, are facing capital outflows as investors shift funds to the dollar, on which interest rates look set to rise.
U.S. housing starts rose to a near eight-year high in July as builders ramped up construction of single-family homes, supporting the case for a rate hike.
Many investors and economists see the Fed as most likely to make its first hike in nearly a decade next month as the labour market continues to improve.
