* Bank supervisors issue joint statement
* Hungary says also signed after forint falls further
* Unicredit CEO pledges support for regional units
* Polish central banker attacks "speculators"

PRAGUE/WARSAW, March 4 (Reuters) - East European banking supervisors complained on Wednesday about negative press over their financial sectors, while the region's biggest foreign lender said its situation was "much better" than has been suggested.
Currencies and stocks in the EU's eastern wing were battered as long-building concerns over banks, growth and external financing reached the front pages of mainstream western media last month, including references to it as "the sub-prime of Europe".
Policymakers have tried to fight that with public statements and policy moves, and Polish, Czech, Romanian, Bulgarian and Slovak bank supervisors on Wednesday decried "publicly announced initiatives" about banks' exposure to central and Eastern Europe, which they said undermined efforts to uphold stability.
"The published information... are often oversimplified and misleading, and it can have a negative impact on banks that are operating in these countries," the supervisory authorities said in a statement published on the Slovak central bank's website.
"Such self-fulfilling speculation totally disregards fundamental economic developments in the CEE countries and creates misperceptions that could inevitably be detrimental to both the CEE region and Europe as a whole."
Analysts, who note the once-booming region is facing at best a sharp slowdown in growth, were unimpressed and said the statement would do little to calm market nerves.
Hungary, long the region's sick-man, also said later that it had signed the statement, but only after markets punished the forint currency, which fell 1.25 percent to a lifetime low against the euro.
The Polish zloty and Czech crown were roughly stable and some analysts said that could be a first sign that investors were starting to favour the region's stronger economies over those which look more vulnerable to a credit squeeze.
They also said the statement looked at odds with Polish and Czech policymakers' efforts to underline their better prospects for growth and lower reliance on external financing than Hungary or Latvia, which have already sought IMF-led bailouts.
The supervisors' statement did not specify what it meant by "publicly announced initiatives", but the Czech central bank has criticised publications including the Economist and the Financial Times for using erroneous data and painting too bleak a picture. Full text at [

SPECULATORS
One concern is the high number of Swiss franc and euro- denominated loans in Hungary, Romania and Poland that have jumped in price for borrowers who are struggling to pay them back with domestic currencies that have fallen by as much as a third against those units since last summer. That has sparked speculation that the handful of Western banks that provide most of the region's funds outside of the Czech Republic, Poland and Slovakia may pull back financing.
The head of Italian bank UniCredit <CRDI.MI> said it would support its units in eastern Europe, echoing statements by others including Austria's Erste <ERST.VI> and Raiffeisen <RIBH.VI>.
"Clearly we support the banks that make up part of the group in the area," Chief Executive Alessandro Profumo said. "Today, no defaults are foreseen for these countries and, looking at the data, the good performances continued in January as well."
But the gloom has led to a selloff in assets and prompted some players to bet against the region's most liquid currencies as the economic slowdown tightens its grip and growth suffers.
Polish central bank Governor Slawomir Skrzypek criticised "speculators", a growing trend in the region's largest economy where media and politicians have blamed foreign investment banks for a 33 percent drop in the zloty currency since July.
"Our aim should be to implement measures that would limit incidence of granting public help to financial institutions that speculate on financial markets of the new member states and emerging economies," Skrzypek said.
"I shall endeavour to initiate a discussion on this subject within the ECB and the European Commission."
Analysts were sceptical such a move could gain any ground, particularly with western EU members scrambling to uphold their banking sectors with billions of euros in capital injections and in some cases the outright nationalisation of flagging lenders.
EU leaders shot down a Hungarian proposal for an 180 euro regional bailout package at the weekend, but diplomats say some sort of deal could include EU and IMF funds, ECB credit lines, and other measures to help countries deal with financing needs.
