NEW YORK, March 22 (Reuters) - The euro fell to a three-week low against the dollar on Monday, still pressured by concern about whether Greece will be able to secure aid this week to help service its ballooning debts.
Traders are cautious before the March 25-26 summit of European Union leaders. European leaders sent out conflicting signals at the weekend over aid to Greece, with Germany urging Athens to solve its debt problems alone while Italy strongly backed EU support. [

Midway through the New York session, the euro <EUR=> was little changed from the prior close at $1.3526, in a technical rebound off the session low, its lowest since March 2. It traded at around 1.4327 Swiss francs <EURCHF=>, teetering near a 17-month low hit late last week, and touched its lowest in over a week against the yen <EURJPY=>.
"It seems there's agreement there will be some sort of assistance to Greece, but it's not clear what form that will take," said Carl Hammer, SEB currency strategist in Stockholm, adding this would keep the euro under selling pressure.
Splits within the EU over how to help Greece have prompted a sell-off in the single currency, knocking it down 10 percent since December.
Germany's foreign minister, Guido Westerwelle, said on Monday he did not want any German or EU money put forward as financial aid for Greece as it would take the pressure off Athens to put its public finances in order. [
].The euro did come off the session low after failing to breach the $1.3450 level, strong support since May 2009, said Joseph Trevisani, chief market analyst at FX Solutions in Saddle River, New Jersey.
The dollar remained rangebound versus the yen at 90.12 <JPY=>, with support around 89.75 and resistance just over 91.00 yen.
The Australian <AUD=> and New Zealand dollars <NZD=> slipped 0.1 percent and 0.5 percent, respectively, against their U.S. counterpart. The commodity-linked currencies are considered to be higher risk.
SUMMIT AHEAD
Greece said at the weekend it could go without borrowing until the end of April but is pressing its EU partners for a concrete standby package to help bring its borrowing costs down. [
]."This brinkmanship between Greece and the rest of the region is likely to come to a head this week," analysts at JPMorgan said in a note to clients. "If the rest of the region does not propose something that is acceptable to the Greeks at this summit, then the Greeks may well go to the IMF."
Analysts expected such uncertainty to keep the euro weak, even as data from the Commodity Futures Trading Commission showed speculators' net short positions on the euro fell to 46,341 contracts last week from 74,551 the week before. [
]Currency players also continued to watch a spat between Washington and Beijing over the yuan, with China's commerce minister saying it would retaliate if the U.S. labeled it a currency manipulator. [
