A senior German official said on Tuesday there was no reason to believe Greece would be in default after a 300 million euro payment to the IMF falls due on June 5.

Separately, reports Reuters, euro zone officials said deputy finance ministers would hold a teleconference on Thursday to follow up on days of negotiations between representatives of Greece and creditors the International Monetary Fund (IMF), the European Central Bank and the European Commission.

Greece must repay four loans totaling 1.6 billion euros ($1.76 billion) to the IMF next month, starting with a 300 million euro payment on June 5.

If no deal is reached within EU/IMF for new loans to be disbursed to Athens, Greece is likely to default on the IMF loan repayment. This would start a process that could lead Greece out of the euro zone.

But in Berlin a senior German official, speaking on condition of not being named, said it was encouraging that Greece had signaled its desire to meet the looming debt obligations.
