SYDNEY, Nov 15 (Reuters) - Asian stocks fell to two-week lows on Monday while the dollar rose as worries that China will tighten monetary policy and persistent concerns about the euro zone debt crisis kept investors cautious.
European shares are expected to open lower, extending losses for the fourth session, hurt by concerns over Ireland's debt woes and a sell-off in metal prices.
Bargain hunting in early Asian trade quickly gave way to more selling as Chinese stocks <
> struggled following a 5.2 percent slide on Friday, when fears China will lift rates gripped markets.Analysts expect more market volatility towards the year-end as Chinese authorities are seen taking further steps to keep in check liquidity in the financial system.
"An imminent interest rate rise after recent bank reserve increase is still very likely," said a trader at a Shanghai securities house.
Reversing earlier gains, the MSCI index of Asia Pacific stocks outside Japan <.MIAPJ0000PUS> fell 0.7 percent to reach lows not seen since Nov. 1. On Friday, the index slid 1.9 percent to post its biggest one-day percentage fall since late June.
There was also little clarity on Ireland's funding problems after the country did not rule out the possibility it may have to turn to Europe for help in dealing with its debt crisis, but said no application had been made for assistance yet. [
]Markets drew no comfort from the G20 and APEC meetings, which left leaders of the world's most powerful economies little closer to agreeing on how to prevent fresh crises.
Many analysts said markets had been due for a pullback regardless, as profit taking set in after a two-month-long rally and traders prepared to close their books heading into the year-end.

The dollar reversed losses against a basket of major currencies <.DXY>, climbing 0.2 percent after the 10-year Treasury note yield <US10YT=RR> rose to a two-month high at 2.823 percent.
"Comments from Richmond Fed President Lacker that he opposed the Fed's new round of QE and the policy was more dangerous than it is worth sparked the initial move, leading to broad based USD short covering," said Sue Trinh, currency strategist at RBC in Hong Kong.
This saw the dollar climb to 82.77 yen <JPY=> from 82.39 yen late in New York on Friday, and the euro <EUR=> slip back below $1.3700. Commodity currencies such as the Australian dollar erased earlier gains.
Further hurt by renewed pressure on commodity prices, the Aussie dollar <AUD=D4> retreated to $0.9820 from a session high around $0.9900 and was down some 3.5 percent from a 28-year high around $1.0182 set last week.
On the London Metal Exchange (LME), benchmark copper <CMCU3> fell 1.3 percent to $8,505 a tonne, extending Friday's 3 percent slide. Gold <XAU=> was a touch lower on the day at $1,364.09 an ounce, but still off a one-week low of $1,359.70 seen on Friday.
U.S. crude oil <CLc1> edged 0.1 percent lower to $84.81, and was about 4 percent below a 25-month high of $88.63 hit last Thursday.
