**Greece has been told that it must make further spending cuts or face sanctions, the eurozone chief has said.**Jean-Claude Juncker told German radio that Greece must understand that other eurozone members are not prepared to pay for its mistakes.
After the European Union vowed to helped Greece last week, the tone has turned harsher this week as talk of a bail-out proves unpopular.
Greece’s woes have sent the euro down to a nine-month low recently.
Mr Juncker - chairman of the 16 nations that share the single currency and also Luxembourg’s prime minister - has said Greece agreed to outline additional cuts in March if necessary.
He added that further measures would be imposed if Greece’s debt reduction plans were not shown to be on target by 16 March.
‘Completely wrong’
Greece’s debt crisis is “first and foremost a Greek problem and an internal Greek problem,” Mr Juncker said.
“The financial markets are completely wrong if they think they can destroy Greece,” he added.
Europe’s leaders pledged to help Greece last week - without spelling out exactly what they were willing to do.
“We won’t abandon Greece,” French Finance Minister Christine Lagarde told reporters. “It’s clear that we are all in this together.”
Greece is trying to reduce its giant public deficit from 12.7% - more than four times what single currency rules allow.
It has pledged to reduce this to 8.7% during 2010 under an austerity plan that involves major cuts in public spending.
But those plans are hugely unpopular with the Greek public and massive strikes have already been scheduled.
Greece’s Finance Minister George Papaconstantinou said that he wanted the other eurozone nations to release details of their planned bail-out for his country to ease market fears that the country could default on its debts.
But Mr Juncker said it would be “unwise” to publicly detail “the measures we are putting in place”.
Mr Papaconstantinou has said repeatedly that his country isn’t asking for financial help from Brussels.
Ministers and bank officials from the eurozone continue to meet in Brussels on Tuesday.
