"What we want is a deal. But if there is no deal and if we see that Germany remains unbending and wants to blow Europe apart, then we have the obligation to go to Plan B. Plan B is to get funding from another source," Kammenos told Greek television channel Mega late Monday night, according to Reuters.
The minister noted that Greece could seek funds from "the United States at best, it could be Russia, it could be China or other countries."
Kammenos is a minister from the political party Independent Greeks, a coalition partner in the government of Alexis Tsipras' Syriza. The new government came to power on a promise to oppose austerity in elections held last month.
Russia has shown interest in infrastructure projects in the country, including ports, coal prospecting and geothermal power stations.
