The European Union is poised to activate an aid plan to meet cash-strapped Greece's financial needs 'at any time,' President Nicolas Sarkozy said Friday. Sarkozy spoke at a joint news conference after talks with visiting Italian Prime Minister Silvio Berlusconi. 'A supporting plan has been aproved by all eurozone members. We are ready to activate it at any time to come to Greece's aid,' Sarkozy said with Berlusconi by his side. Reiterating that Greece is a part of the eurozone, the Italian leader emphasized that European members have a 'responsibility' for Greece. If there is no united salvage, 'there will be a negative impact on the euro and thus the eurozone,' Berlusconi said. The European Union released last month a rescue plan based on relief from the International Monetary Fund and within the EU itself, but recent reports leaked the possibility that Greece may bypass the IMF, which revived wide doubts in financial markets. Yields on Greek 10-year bonds continued to hover above 7 percent on Wednesday amid concerns about a credit default. Sources confirmed that EU President Herman van Rompuy said Friday that the European Union was ready to intervene along with the IMF if necessary. When answering questions about Italy's own financial struggles, Berlusconi asserted confidence. He said Italy could well handle its domestic fiscal situation, which is much better regarded than that of Greece. However, Berlusconi's remarks differed from a warning issued by the Organization of Economic Cooperation and Development two days ago. The OECD's chief economist said Italy had long been 'a low- growth and high-debt country' and needs to start fiscal consolidation as soon as possible.
