Fars was particularly interested in Thailand’s role as a member of the Board of Governors of the International Atomic Energy Agency (IAEA) in relation to the Iran nuclear issue, as well as in Ambassador Kriangsak’s initiative of hosting informal brainstorming meetings in Tehran among ambassadors from several key player countries in this matter. Ambassador Kriangsak explained at length that Thailand always discharged her functions at the IAEA with transparency, impartiality and fairness, and that Thailand stayed well clear of any effort to politicize the Iran nuclear issue. This explanation was conveyed by the Ambassador to President Mahmoud Ahmadinejad and to Foreign Minister Manouchehr Mottaki of Iran when they met. The Ambassador emphasized that Thailand was opposed to nuclear weaponization. As an initiator of the 1971 Declaration of the Zone of Peace Freedom and Neutrality (ZOPFAN) and the 1995 Southeast Asia Nuclear Weapon-Free Zone Treaty (Bangkok Treaty), Thailand believed that every State Party to the Nuclear Non-Proliferation Treaty (NPT), including Iran, had to respect the NPT’s 3 pillars: non-proliferation, disarmament and peaceful use of nuclear energy.

The informal brainstorming meetings initiated and hosted by Ambassador Kriangsak had the purpose of facilitating exchange of views and analyses and exploring options which might be useful to the participating ambassadors when they submitted recommendations or suggestions to their respective governments. Ambassador Kriangsak expressed his fervent hope that after the international community of nations reached a peaceful solution on the Iran nuclear issue and the sanctions imposed by the UN Security Council against Iran were lifted, Iran, with the second largest oil and natural gas reserves in the world, would enjoy a leading role in the world economy as she rightly deserved.  

Economically, Iran is the largest importer of Thai rice in the Middle East (at approximately 1 million ton per year).

Culturally, Persians in the royal courts of Siam during the Ayudhya Kingdom  introduced to Siam/Thailand the religion of Islam, Islamic cultures and Islamic traditions, including the institution of Sheikh’al Islam (จุฬาราชมนตรี). Some Iranian food—e.g., Chelo morgh (rice with chicken, or ‘kao mok kai’)—is popular in Thailand. Several Persian words have become Thai words, such as Jipoon (Japan), farang (Western foreigner), kulab (rose), caravan, nav (navy นาวี),  kuchek kuchek (knickknack กระจุกกระจิก), and chatr (royal umbrella ฉัตร)
