Greece plans to meet all its debt obligations, its finance minister Yanis Varoufakis has insisted.
When asked on Greek radio whether Athens would make a €300m payment to the IMF on Friday, he said: "As finance minister I cannot answer such a question other than to say that the Greek state aims at always repaying all of its beneficiaries."
Greece will not now make that payment until the end of the month, when it will pay a total sum of €1.5bn.
Russian president Vladimir Putin has criticised the European Union for not doing enough to help Greece's economy grow.
Greek finance minister tells ITV News that he hopes the plan can be negotiated.
