TOKYO, Oct 24 (Reuters) - An HSBC survey of Chinese manufacturers suggesting growth was recovering in the world's second largest economy helped trim declines in Asian shares on Wednesday, though investors remained wary due to weak corporate earnings worldwide and enduring worries over a global slowdown.
European shares will likely rise, with financial spreadbetters expecting London's FTSE 100 to open up as much as 0.3 percent and Paris's CAC-40 seen opening 0.9 percent higher.
The MSCI index of Asia-Pacific shares outside Japan slid 0.2 percent. China's Shanghai Composite was up 0.3 percent and was the region's best performing index. Hong Kong's Hang Seng was little changed.
Japan's Nikkei average recovered slightly from its earlier 1 percent drop but was still down 0.5 percent dragged down by weakness in shares of export-oriented firms.
The China HSBC Flash Manufacturing Purchasing Managers Index (PMI) rose to a three-month high of 49.1 in October, also registering the most robust order books since April, signalling a strengthening recovery.
"Recent data have suggested that Chinese growth may have bottomed out last month, helping to improve market sentiment as U.S. economic figures have also been hinting at a brightening recovery trend recently," said Kyoya Okazawa head of global equities at BNP Paribas in Tokyo.
In a sign of capital flows back to the region, particularly into Hong Kong, the territory's de facto monetary authority has intervened thrice in the currency market since last Friday to curb the Hong Kong dollar's strength after it hit the top-end of its trading band.

Shares of market heavyweight Samsung Electronics fell a percent while Hyundai Motor was off 2.7 percent.
The dollar was steady against the yen at 79.82 yen, having hit its highest since early July of 80.02 on Tuesday.
The Australian dollar rose to a high of $1.0317 after the PMI report on China, having earlier risen from around $1.027 following data showing Australian consumer prices increased a surprisingly large 1.4 percent last quarter, lowering expectations for interest rate cuts.
The Aussie rose 0.5 percent against the yen to 82.33 yen , helping the euro to steady against the yen at 103.70 yen. The euro touched a 5/1-2 month high against the yen of 104.45 on Tuesday.

On Tuesday, U.S. stocks fell, with the Dow industrials suffering the biggest drop since June 21 after DuPont and United Technologies showed profit growth slowing, adding to a string of disappointments from companies falling short of Wall Street's expectations.
U.S.-listed shares of foreign companies slid across the board on Tuesday, also on fresh worries over the euro zone's debt crisis as Spanish bond yields rose after Moody's Investors Service downgraded five of Spain's regions.
