Asian shares erased modest gains to edge lower on Wednesday as cautious investors waited for more clues about the global growth outlook, while a pause in the yen's declines spurred profit taking in Japanese equities after their recent rally.
The World Bank on Tuesday sharply cut its 2013 outlook for the world economy to 2.4% from its last forecast in June of 3%, blaming an unexpectedly sluggish recovery in developed countries for holding back global growth.
The MSCI's broadest index of Asia-Pacific shares outside Japan wiped out an earlier 0.2% rise to fall 0.1%.
"There's no real momentum in the market before China's fourth quarter GDP figures on Friday, so shares are likely to coast, with individual stocks aligning with earnings expectations," said Kim Sung-hwan, an analyst at Bookook Securities in Seoul.
Bank stocks pulled Australian shares up 0.3% and South Korean shares advanced 0.3%. Hong Kong shares dropped 0.3% and Shanghai shares eased 0.3%.
"We've just seen the banks do well a bit today, they're getting demand for that yield play," said Stan Shamu, market strategist at IG Markets in Sydney, pointing to the Australian bank sector's strong dividends.

Japan's benchmark Nikkei average shed 1.5%, sharply reversing Tuesday's rally that lifted the index to a 32-month closing high, as the yen took a break from its recent heavy selling. The weak yen has been a catalyst for the Nikkei's 24% gain over the past two months.
"It's a correction. Some exporters' gains are legitimate, but others aren't, so I am selling exporters which have gained while their fundamentals are still poor such as Panasonic," said Makoto Kikuchi, Chief Executive of Myojo Asset Management in Tokyo.
The dollar and the euro extended losses against the yen, after a Japanese official on Tuesday sparked selling by warning of damage from excessive yen weakness through rising import prices.

Reallocation underway?
The euro eased 0.1% against the dollar to $1.3293, after reaching an 11-month high of $1.3404 on Monday.
The euro was pressured by a weak economic report from Germany as well as comments from the chairman of the euro zone finance ministers, Jean-Claude Juncker, who on Tuesday said the euro was "dangerously high" without elaborating.
The single currency fell 0.3% against the Swiss franc at 1.2365, having hit a 13-month high of 1.2413 francs on Tuesday. The Swiss franc has been hit by receding safe-haven bids as falling yields in deeply-indebted countries such as Spain and Italy eased concerns about the euro zone's debt crisis.
Reversals in the strengthening trend for the Swiss franc and the yen may suggest asset reallocations are taking place.
