The World Bank reported that after sanctions were removed in 2016 there were many positive economic developments in Iran. In November 2018 the US reimposed sanctions and requested India, China and EU countries, to stop working with Iran. Sanctions are major causes of food insecurity, mass suffering, and eventual high poverty rates. Oil is the largest source of income. When there is no oil coming, there are no US dollars. Everything purchased in Iran is with US dollars. ‘No dollars’ causes the value of the Iranian rial to fall drastically, causing many companies to go bankrupt and having to let a lot of employees go. Sanctions increase the gap between the rich and poor. However there are a number of Christian business and mission initiatives established in Iran, including church-planting via small businesses. See
