Iran is currently China's third largest supplier of crude, providing Beijing with roughly 12 percent of its total annual oil consumption.
According to the figures released by China's General Administration of Customs in January, China's crude oil imports from Iran reached 2.5 million tons (mt) in December 2012, up 43 percent from November.
Meantime, Iran and India which have deep historical and cultural relations are now seeking to further expand political and economic ties.
India, the world's fourth-largest petroleum consumer, is Iran's second largest oil customer after China and purchases around $12bln worth of Iranian crude every year, about 12 percent of its consumption.
Iran is also one of the most important donors to Afghanistan which has kept its promises to help to the reconstruction of the war-hit country.
Iran has built some roads, power transmission lines, and border stations, among the other infrastructure projects which would better link the two nations.
Iran has also contributed more than $50mln annually to Afghan anti-narcotics efforts in the last decade.
The neighboring counties of Iran and Iraq have enjoyed growing ties ever since the overthrow of the former Iraqi dictator, Saddam Hussein, during the 2003 US invasion of the Muslim country.
