Iran on Sunday appointed Mohammad Reza Sabouri as its new ambassador to Belarus, FNA reported.
Sabouri replaced Seyed Abdollah Hosseini who was Iran's envoy to Minsk for four years.
Sabouri had previously held several positions at the Iranian foreign ministry such as deputy director general for Commonwealth of Independent States (CIS) and the Caucuses, head of bilateral and multilateral economy offices, deputy director general for economic cooperation, and Ambassador to Kyrgyzstan.
Tehran and Minsk have in recent months increased efforts to start a jump in mutual cooperation.
Last week, Belarus Foreign Minister Vladimir Makei renewed his call for the expansion of the bilateral ties and mutual cooperation with Iran.
The Belarus foreign minister made the remarks in a farewell meeting with Hosseini in the capital, Minsk at the time.
"Many developments have taken place in Iran-Belarus relations in the past four years," Makei said praising the wide strides taken in the expansion of the two countries' relations.
The Iranian ambassador, for his part, said that Iran's private sector has actively taken part in Belarus' projects, and added, "With the completion of the Belarus' pending projects by Iran's private sector, the value of Iran's investment in that country will hit $2bln."
"The capacity for cooperation between Tehran and Minsk is potentially extraordinary and Belarus is an exceptional, and in the meantime, unknown opportunity for our country," Hosseini told FNA at the time.
"At present the two countries cooperate in six to seven areas and these fields of cooperation would grow to fifteen according to the plans," he added.
Iran and Belarus have recently widened their areas of economic cooperation. The two countries signed a Memorandum of Understanding on road transportation cooperation in March.
The two countries also announced in March that they plan to establish a join trading company to help expand their bilateral ties and exchanges.
