Russia and Iran have signed a deal to expand nuclear energy facilities in Iran, with Russia funding the construction of a new nuclear plant and the completion of phases two and three of the Bushehr power plant. The announcement comes as US and Iran officials meet for a third round of nuclear talks in Oman. In addition to the nuclear deal, Russia and Iran have also agreed to supply Iran with 55 billion cubic meters of Russian gas per year and develop seven oilfields. The two countries are aiming to increase the flow of Russian gas and strengthen Iran's position as a regional gas hub. The signing of a strategic partnership treaty between Russia and Iran earlier this year further solidifies their growing alliance.
