A standoff in Ukraine, signs of weakness and other risks in China's economy and a massive fall in copper prices are spooking investors, though a flat close on Wall Street and some positive regional data helped to underpin some markets.
MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.9 percent, recouping a large chunk of its losses the previous day, with Australian shares gaining on strong local employment data.
Japan's Nikkei rose 0.5 percent as Japanese machinery orders beat expectations, though the gain came only after a 2.6 percent drop the previous day, when both European shares and emerging market shares fell to one-month lows.
"What we're seeing today is a reaction to yesterday's sharp decline based on price (valuation) merits," said Hana Daetoo analyst Chang Hee-jong.
"But concerns about China remain the biggest issue for the market, and this will continue to affect markets throughout the first half of this year."
Copper - seen as a good gauge of global economic strength because of its extensive use - stabilised at $6,508 a tonne, keeping some distance from a four-year low at $6376.25 hit on Wednesday.
Still, after a drop of around 7 percent so far this month, investors are worried about a possible unraveling of Chinese loan deals using copper as collateral, which could add more pressure on copper prices.
On Wall Street, the S&P 500 reversed early losses and ended nearly flat, outperforming many others thanks in part to a string of positive data on the U.S. economy.
Investors will keep a close watch on Chinese data due at 0530 GMT, including urban investment, industrial output and retail sales, which will follow a disappointing series of February data in recent days.

The diplomatic stalemate between Russia and the West over Ukraine has also led investors to buy traditional safe haven assets.

U.S. Treasuries have erased all their losses after last week's strong payrolls data, with the benchmark 10-year yield at 2.74 percent versus its six-week high of 2.82 percent hit on Friday.
In the currency market, the Swiss franc was little changed after hitting a two-and-a-half year high of 0.8734 franc to the dollar, while the Japanese yen, which is under pressure from the Bank of Japan's easing, also ticked up slightly.
Going against the tide of risk-off trading, the New Zealand dollar hit a five-month high of $0.8527 after the country's central bank raised rates as expected and pointed to further tightening ahead to curb inflationary pressures.
The Australian dollar jumped 0.8 percent to $0.9062 after surprisingly strong local employment data.
U.S. crude futures traded near one-month lows hit on Wednesday after Washington announced a surprise plan for a test release of strategic oil reserves, trading at $98.12 per barrel, near Wednesday's low of $97.55.
