LONDON, March 3 (Reuters) - The euro rose on Wednesday after the Greek government endorsed a 4.8 billion euro austerity package, but markets were wary over whether it would be enough for Athens to win financial support from its European partners.
The euro rose roughly half a U.S. cent after a government source told Reuters the Greek cabinet decided on the plan, which included a rise in value added tax to 21 percent and a cut in public sector salary bonuses by 30 percent. [
]Market reaction was limited after an official announcement disclosed more details of the plan [
].While sentiment remained fragile, "there would appear an increasing chance that in the coming days developments in Greece and the euro zone will help stabilise confidence and lift the euro from oversold levels," said Derek Halpenny, European head of global currency research at Bank of Tokyo-Mitsubishi UFJ.
Greek bond yield spreads also narrowed on the news.
But the euro's gains were limited ahead of a key meeting between the Greek and German leaders scheduled for Friday.
"The importance of today's announcement stems from the implications it has on the meeting," said Halpenny. "Approval by Germany of today's fiscal announcement would imply financial support for Greece if needed."
At 1214 GMT, the euro was 0.2 percent higher on the day at $1.3637 <EUR=>. Stop-losses were seen at $1.3680 with a technical target at $1.3693, traders said.
On Tuesday, the euro fell as low as $1.3432, its weakest since mid-May 2009. Greece's fiscal crisis has helped drive the euro down nearly 10 percent against the dollar since December.

The market was also keenly eyeing the fate of a sale of 10-year Greek government bonds expected soon.
"The sale will be the big test for the euro," said Antje Praefcke, currency strategist at Commerzbank in Frankfurt.
Sterling edged higher against the dollar <GBP=>, boosted by higher-than-expected services activity data, further bouncing back from a 10-month low hit on Monday.

Concerns over debt in the euro zone were likely to keep interest rates low, and no change is expected at a European Central Bank policy meeting on Thursday.
"The medium-term implications of such aggressive fiscal austerity measures in Greece and in many other peripheral countries will keep inflation very low in the euro zone and curtail ECB action well into 2011," BTM's Halpenny said.
All economists polled in a Reuters survey expected the ECB to hold interest rates at a record low 1.0 percent.
The dollar slipped across the board as traders trimmed long positions in the U.S. currency, which last week had built up to their highest levels since September 2008.
The dollar <JPY=> fell to 88.47 yen in Asian trade, according to trading platform EBS, its lowest since December.
The dollar index fell 0.3 percent to 80.238 <.DXY>.
Traders refrained from taking on big positions before the U.S. non-farm payrolls report due on Friday.
Investors awaited U.S. ADP employment report at 1315 GMT, which is forecast to show 20,000 jobs were lost in February versus a loss of 22,000 in January.
