* Finance minister resigns over reform disagreements
* Had sought 15 percent cut in public wages, 20 percent in pensions
* Acting finance minister eyes 10 percent cuts in both
* Says package must be acceptable to IMF as loan talks loom
BELGRADE, July 14 Serbia's acting finance minister said on Monday he aimed to ease back on previously announced cuts to pensions and public sector wages, looking to soothe market nerves two days after his predecessor resigned.
Lazar Krstic stepped down as finance minister on Saturday, saying he did not have the support of Prime Minister Aleksandar Vucic for tough measures Krstic sought in order to rein in public spending and cut Serbia's ballooning budget deficit.
With loan talks with the International Monetary Fund looming, Krstic had sought a public sector wage cut of at least 15 percent and 20 percent for pensions.
His interim replacement Dusan Vujovic, who is expected to take over permanently, said on Monday he would look to cut both public wages and pensions by 10 percent.
"We will try to stay within what is reasonable, and 10 percent is reasonable," Vujovic told Serbia's state broadcaster. "The entire package must by acceptable to the International Monetary Fund and global markets."
Krstic had also called for a minimum of 160,000 of Serbia's roughly 700,000 public sector workers to be laid off over the next two years, as the best way to curtail a budget deficit threatening to exceed eight percent of output.
Vujovic said his aim was to cut the deficit to 130 billion dinars (1.1 billion euros) by the end of 2017, from an initially planned 182 billion dinars (1.56 billion euros) this year.
The government is expected to revise the 2014 budget and increase its deficit forecast in September.
