"Well, we can imagine any situation, so if such [a] petition is submitted to the Russian government, we will definitely consider it, but will take into account all the factors of our bilateral relationships between Russia and Greece, so that is all I can say. If it is submitted we will consider it," Siluanov told CNBC in an exclusive interview in Moscow on Thursday.
Siluanov's comments come two days after Greece's new left-wing-led government distanced itself from calls to increase sanctions against Russia—indicating that Greece could be looking east to Russia for support.
On Tuesday, EU leaders issued a statement calling for "further restrictive measures" to be considered against Russia with regard to its involvement in the ongoing conflict in eastern Ukraine.
After the statement, a representative for Greece's newly elected Syriza party reported that the EU's statement was made "without our country's consent" and expressed "dissatisfaction with the handling of this."
On Thursday, Siluanov said that while Western-imposed sanctions against Russia thus far had been harmful, the country has managed to adapt.
"The sanctions that have already been imposed against Russia did have (a) negative effect on us. However, Russia companies have adjusted and the Russian balance of payments has adjusted. (The) ruble weakened and as you might see, life still goes on here and we just keep on living," he said.
