LONDON, Dec 23 (Reuters) - The euro steadied against the dollar and the Swiss franc on Thursday, helped by supportive comments from China, but analysts said the outlook for the single currency was shaky, with fresh losses expected into 2011.
Liquidity was at a premium in currency markets ahead of year-end, with traders saying flows were having a bigger impact on price than fundamentals.
A Chinese Foreign Ministry spokeswoman said China was willing to help countries in the euro zone return to economic health and would support the International Monetary Fund bailout package for the bloc. [
]A Portuguese newspaper report on Wednesday suggested China was ready to buy significant amounts of Portuguese debt to try to instil confidence in the country's ailing economy.
But the single currency's outlook remained shaky at best and more losses into 2011 are seen likely as the euro zone debt crisis looks set to drag on.
"We expect further weakness for the euro by the end of the first quarter of 2011, and in the near term a break of the 200-day moving average will be important," said Elsa Lignos, currency strategist at RBC Capital Markets.
The euro was flat against the dollar <EUR=> at $1.3100, close to the 200-day moving average at $1.3091. In the past week, the euro has fallen about 1 percent against the greenback.
The euro was flat at 1.2466 Swiss francs <EURCHF=>, hovering near an all-time low of around 1.2448 hit on Wednesday.
"As long as there are periphery concerns in the euro zone, a lower euro/Swiss is very hard to fight," Lignos said.
Investors have been flocking to the safe-haven status of the Swiss franc and shifting out of euros on worries that the euro zone debt crisis will rumble on.
"Our next target for EURCHF is 1.2400," BNP Paribas strategists said in a client note. "The CHF is currently driven by capital rather than trade flows and thus remains well supported against the EUR as deposit inflows continue."
AUSSIE DOLLAR FIRM
The Australian dollar was back at parity against the greenback thanks to optimism about the global economy, which has supported commodity prices <.CRB> and global stocks <.MIWD00000PUS>.
The diverging moves showed investors favoured safe havens like the Swiss franc within Europe, but that they were also keen on currencies deemed riskier like the Aussie given the generally more upbeat outlook, particularly for emerging economies.
Trading, however, was thin with Tokyo shut for a public holiday and as the year-end holidays loomed.

The dollar was down around 0.7 percent at 82.95 yen <JPY=> after taking out stop-losses in thin liquidity. Traders said an option barrier at 83.15 had been eroded in Asia, while support at the top of the Ichimoku cloud gave way in Europe at 83.08. The base of the cloud was seen as the next support, at 82.07.
Yen strength knocked the euro <EURJPY=R> down 0.6 percent to 108.78 yen, with a French bank highlighted as the major seller.
The dollar index <.DXY>, which tracks the greenback's performance against a basket of major currencies, fell about 0.2 percent to 80.562.
Meanwhile, the New Zealand dollar stood at $0.7448, having recovered from a brief fall below $0.7400 in immediate reaction to data showing a contraction in the New Zealand economy for the first time in six quarters. [
