Sydney - Asian shares began the week on a plaintive note amid losses on Wall Street and worries over China, while investors braced for a Federal Reserve meeting that might take another small step toward lifting US interest rates.
Japan's Nikkei slipped 0.5 percent, while MSCI's broadest index of Asia-Pacific shares outside Japan lost 0.8 percent.
In China, the CSI300 index .CSI300 of the largest listed companies in Shanghai and Shenzhen fell 1 percent, with sentiment still soured by a poor PMI survey on manufacturing.
Australia's main index fell 0.2 percent as mining stocks struggled with the slump in global commodity prices.
Both copper and the Thomson Reuters CRB commodities index hit their lowest in six years. Early on Monday, copper futures were off another 0.1 percent.
The Fed's policy-setting Open Market Committee meets on Tuesday and Wednesday and is considered highly unlikely to lift interest rates just yet, though it does still seem set on a move in September.
“We expect Fed voters to pull the trigger in September, but for the path to interest rate normalisation to be a long one given the global risk profile, the lack of inflationary pressure, and concerns over what moving too quickly may do to asset markets, particularly the dollar, and the wider economy,” said analysts at Australia and New Zealand Banking Group.
Expectations of a hike has slowly pushed up US Treasury yields and widened the dollar's premium over the euro. Yields on two-year US notes pay around 90 basis points more than German debt, near the widest since early 2007.

A first estimate of US economic growth for last quarter is due on Thursday and is expected to show a rebound of 2.7 percent annualised, from the first quarter's weather-induced contraction.

Wall Street has been weighed in part by concerns that a high US dollar and sluggish global demand was pressuring corporate profits, a theme that should wend its way through this week's busy diary of earnings.
As well as blue-chip names such as Pfizer and Exxon Mobil, there are a range of social media stocks that have led the market so far in 2015 including Facebook, Cigna, Twitter and LinkedIn.
In the energy market, Brent crude was quoted 5 cents lower at $54.57 a barrel and near its lowest since March. US crude was off 11 cents at $48.03.
