The United Arab Emirates and China are the two major trade partners of Iran, Head of Trade Promotion Organization of Iran (TPO), Valiollah Afkhamirad told ISNA on Saturday. The official said during the first nine months of the current Iranian calendar year (March 21-December 22), Iran exported 26 percent of its non-oil products to China, while the majority of imports came from the United Arab Emirates. Afkhamirad lamented that there are still significant barriers on the way of Iranian exporters to increase their export level although the government has tried its best to facilitate the process.
