HONG KONG, Dec 22 (Reuters) - Asian shares fell and the dollar retreated on Monday as investors locked in profits from recent gains after weak exports data from Japan and worsening outlooks at blue chips such as Toyota add to the economic gloom.
European shares were also seen lower on Monday though a timid recovery in commodity prices could lend support to recently routed mining and oil shares. [
]The weakening dollar and the prospect of production cuts from OPEC sparked a recovery in oil prices, after prices on Friday had slumped more than 6 percent due to fears of a deep economic slowdown.
Central banks are responding aggressively to the downturn, with interest rates in both the United States and Japan now at near zero, helping support some regional bonds on Monday.
"There is fair bit of unwinding for the Christmas period by the looks of it. A lot of people are away on holidays," said Lucinda Chan, a division director with Macquarie Equities.
The MSCI index of Asia-Pacific stocks outside Japan <.MIAPJ0000PUS> fell 1.8 percent, reversing a rebound that had seen the index climb 16 percent over the prior two weeks.
Regional stock markets have still suffered an ugly year with losses in the MSCI index of more than 50 percent.
Earlier advances on Monday following the U.S. government's $17.4 billion of rescue loans for ailing auto makers last week evaporated as investors locked in gains as they returned their focus towards a weak global economy.
Data on Monday showed Japan's exports plunged at a record annual pace in November. Most tellingly for the region, shipments to Asia dropped the most since 1986, in a clear sign that an economic slump is stretching far and wide. [
]Corporate profits are under threat, and companies are responding with layoffs and spending cuts.
Japanese auto maker Toyota Motor Corp <7203.T> forecast an annual group operating loss of 150 billion yen, its first such loss ever, according to a local newspaper. [
]Elsewhere, global miner Rio Tinto <RIO.AX> <RIO.L> suspended operations at an Australian pig-iron plant for at least three months as it seeks to weather the economic downturn. [
]Regional shares largely fell, led by a 3.4 percent loss in Taiwan's main index <

Still, signs of a willingness to add on risk are emerging as a brutal 2008 comes to a close, though the actions could easily reverse given prevailing caution, analysts have warned.
Portfolio managers have kept shifting funds into Asian equity markets in a sign of more tolerance for risk. Data from EPFR Global showed Asia ex-Japan funds received a fifth straight week of inflows in the week ending last Wednesday.
In Japan, a poll of portfolio managers showed investors had slightly increased their equity holdings in November, while paring their levels of cash and bonds. [
]On Monday the dollar and the yen fell against the euro as currencies offering higher-yields benefit. Despite the U.S. and Japanese rate cuts, European policymakers are seen more reluctant to cut rates from 2.5 percent.
The euro rose 0.7 percent from late New York trade on Friday to $1.4013 <EUR=>. That marks a partial reversal from Friday, when the dollar posted its biggest daily gain against the euro in almost two months after the U.S. auto bailout.
The euro also climbed against the Japanese yen, by 1.3 percent to 125.84 yen <EURJPY=>.
Oil prices <CLc1> climbed 64 cents to $43.00 a barrel, buoyed by a weaker dollar and as top OPEC producers talked tough about enforcing compliance to their announced record output cut.
Government debt benefitted as central banks worldwide are grappling with the severe downturn in the global economy by cutting interest rates.
March Japanese government bond futures climbed 0.25 point to 139.93 <2JGBv1> after touching 140.14, the highest since mid-September.
Japan's benchmark 10-year yield <JP10YTN=JBTC> dipped 1 basis point to 1.215 percent, after touching 1.200 percent, the lowest since July 2005.
Japanese government bonds benefitted as well after the BOJ upped the amount of debt it would purchase each month as part of its monetary easing measures. (Additional reporting by Kim Yeon-hee in SEOUL and Satomi Noguchi in TOKYO; Editing by Lincoln Feast)
