Iran is, however, hopeful that in addition to EU, China and Russia, and partly India, will stand beside them to overcome the dire damaging effects of this ban. Iran has taken steps to establish close relations with these countries for several years. Iran's main export-oriented oil China and India, both countries have imported oil from Iran in the last few years. Since the Obama government withdrew its sanctions on Iran in 2016, the two countries have become the main importer of Iranian oil.
India hopes that if there is a close relationship with Iran, it will bring benefits to the sugarcane. To that end, they have signed contracts for huge financial investment for the development of the trade port of Iran. Indian policy makers hope that India will be able to build trade relations with Afghanistan after Pakistan starts the port.
Russia is also interested in long-term economic with Iran. During a visit to Beijing in 2016, Russian President Putin signed a multilateral trade agreement with China. Welcoming the agreement, the two parties said that they are not only interested in expanding relations in trade, they want 'Friendship for Life'.
