Thai Prime Minister Prayut Chan-o-cha received the Iranian president in a formal welcome ceremony, followed by a meeting of high-ranking delegations.
Heading a political and business team, the Iranian president embarked on a tour of Southeast Asia on Wednesday that took him earlier to Vietnam and Malaysia.
In Thailand, President Rouhani is going to deliver a speech at the ACD summit and meet foreign leaders on the sidelines of the conference.
