Masoud Pezeshkian will start his four-day visit to Yerevan on August 18, according to Armenian media outlets.
Iran's government or state-run media have not yet confirmed the visit which is expected to focus on the US-Armenia deal on a Caucasus corridor.
On Friday, Trump brokered a peace deal between Armenia and Azerbaijan, which gives Washington leasing rights to develop the Zangezur transit route connecting Azerbaijan with its exclave, Nakhchivan. It will be renamed the Trump Route for International Peace and Prosperity (TRIPP).
On Monday, Pezeshkian had a phone conversation with Armenian Prime Minister Nikol Pashinyan, during which he urged regional countries to "remain vigilant and cautious in the face of possible schemes by the United States to pursue its hegemonic goals in Caucasus."
He warned that the United States may use the Zangezur project to achieve its objectives under the guise of economic investment or promotion of peace.
On Tuesday, Iranian Foreign Minister Abbas Araghchi said the planned transport route must not change the region’s geopolitics or cut Iran's access to other corridors.
Speaking in a phone call with his Armenian counterpart Ararat Mirzoyan, Araghchi said, “In any decision or action, respect for national sovereignty and the territorial integrity of countries must be fully observed."
