TOKYO, Feb 25 (Reuters) - Asian shares edged higher on Monday but uncertainty facing the global economy capped prices as a private survey showed Chinese manufacturing contracted this month from two-year highs.
European markets are seen rising, with financial spreadbetters predicting London's FTSE 100, Paris's CAC-40 and Frankfurt's DAX would open as much as 0.4 percent higher. U.S. stock futures were steady to suggest a calm Wall Street start.
Investors remain wary of fragility in the global economic recovery, having pushed markets broadly higher over the past few months as pessimism over the euro zone's debt crisis and U.S. budget woes receded.
But now markets are wondering whether Italy's weekend elections will produce a stable government, and the implications of that for euro zone cohesion, while Moody's credit downgrade on Britain weighed on confidence in the pound.

"It's a waiting game at the moment, with the U.S. Fed chief's testimony on Tuesday and the outcome of the elections in Italy due to come. We're not sure if this is the bottom," said Jackson Wong, Tanrich Securities' vice-president for equity sales.
China's HSBC flash purchasing managers' index (PMI) for February slipped to a four-month low of 50.4 from January's final reading of 52.3, which had been the best performance since January 2011. The flash PMI, however, did indicate a fourth consecutive month of expansion, even though it just managed to avoid the 50-mark separating expansion from contraction.
Hong Kong shares were up 0.1 percent and Shanghai shares rose 0.5 percent, but the PMI news pared early gains.
The MSCI's broadest index of Asia-Pacific shares outside Japan was up 0.1 percent, pulled higher by Australian shares which gained 0.8 percent on strong financials and retail stocks.
South Korean shares bucked the trend and fell 0.5 percent, on news that an advocate of aggressive monetary easing was poised to head the Bank of Japan pressured Korean carmakers.
The Nikkei newspaper reported the Japanese government is likely to nominate Asian Development Bank President Haruhiko Kuroda and Kikuo Iwata, both vocal advocates of aggressive monetary expansion, as BOJ governor and deputy governor.

Prime Minister Shinzo Abe on Friday vowed to get the world's third biggest economy growing again as he met with President Barack Obama. The United States and Japan also agreed on language during Abe's visit that could set the stage for Tokyo to soon join negotiations on a U.S.-led regional free trade agreement - the Trans-Pacific Partnership.
"The news of Kuroda (as BOJ nominee) appears to be taken positively by the market, but I think signs of progress towards TPP are vital as it shows Abe is taking leadership in pushing structural reforms, with the TPP being a vital tool to boosting growth," said Tetsuro Ii, the chief executive of Commons Asset Management.
The prime minister's "Abenomics" policy of powerful monetary and fiscal stimulus, with its consequent weakening of the yen, has cheered investors who have pushed the Nikkei average up some 30 percent and the yen down 20 percent against the dollar over the past three months.
The yen touched a low of 94.77 against the dollar, while the euro rose to a high of 124.83 yen.
The dollar fell sharply to below 93 yen last week on media reports that Toshiro Muto, a former financial bureaucrat perceived as less willing to take unconventional steps, was the frontrunner candidate for the top BOJ job.
"The dollar's move this morning is merely a rebound from disappointment on Muto last week. I don't think this topic will be enough to hoist the dollar above 95 yen," said Hiroshi Maeba, head of FX trading Japan at UBS in Tokyo. "No matter who is elected at the BOJ, it will not affect the longer-term trend of a weak yen," he said.
Speculation over the BOJ has been a key factor driving the yen lower recently due to expectations of strong reflationary measures, but fundamental factors such as Japan's deteriorating trade balances and signs of firmer U.S. growth also supported a weakening yen trend.
In the U.S., with five days left before $85 billion is slashed from U.S. government budgets, the White House warned about the harm the cuts will do to Americans.
