Raeisi made the remarks while speaking at the 16th ECO summit held in Uzbekistan's Tashkent on Thursday morning.
Saying that Iran unconditionally supports the activities of ECO, the president added that the organization is a favorable mechanism of economic cooperation in the region.
He also hailed the strong will of all ECO member states to create a safe, stable, prosperous region and to play an effective role in international systems.
Today, the Islamic Republic of Iran, with the support and cooperation of many independent countries and its international partners, is moving to build a just military foundation based on respect and deepening multilateral integration, Raeisi added.
Touching upon the ongoing Israeli regime's crimes in the Gaza Strip, he said that the Islamic Republic of Iran considers the all-round support of the West, especially the American government, to the Zionist invasion of Gaza as the reason for the continuation of this crime.
Referring to the pro-Palestine protests held across the globe in condemnation of the Israeli regime's attacks against Palestinians, the continuation of the Israeli regime's killings and crimes has made all free people impatient and its dimensions and consequences will not be limited to the West Asia region.
"Currently, stopping the attacks and delivering humanitarian aid to the people of Gaza are among the most critical priorities," he added.
Elsewhere in his remarks, Raeisi touched upon the Afghanistan issue, saying, "We are still waiting for an inclusive, responsible and responsive government with the effective presence of all ethnic and religious groups in Afghanistan."
He called on ECO to ECO implement a program to support Afghanistan in helping the noble Afghan people and assisting in the reconstruction and economic development of that country.
