"Delaying adjustment is risky... And it is also not free: it requires additional funding from the creditor countries, because the country still runs a primary deficit," he added.
The government is bracing for a series of meetings starting on Tuesday with inspectors from the European Union and the IMF who will assess progress on agreed reforms, after significant delays as Greece held two general elections in as many months.
Samaras, who missed a crucial European Union summit last week while recovering from eye surgery, was locked in meetings with government officials over the weekend. After being given the green light by doctors on Monday he is expected to meet later in the day with his coalition partners, Evangelos Venizelos of PASOK and Fotis Kouvelis of Democratic Left.
Speaking to Kathimerini in an interview on Sunday, Asmussen said that the troika was willing to discuss tweaking certain aspects of the bailout deal on the condition that these changes do not affect its targets.
"We were always open and we are open to discuss elements of the program as long as we keep the key goals of the program intact. So, let’s say, if he [Samaras] wants to change the mixture of the revenue and expenditure measures this can surely be discussed," Asmussen said, adding: "But with respect to the key results and goals of the program to make Greece more competitive and to reach a debt sustainability situation, I do not see room for change."
