TEHRAN -- President Masoud Pezeshkian here on Thursday proposed a mutual security and non-aggression pact among Muslim countries, calling on Islamic states to respect one another’s territorial integrity and prevent their territory, airspace or facilities from being used to attack another Muslim country.
Pezeshkian made the proposal at the opening of the 40th International Conference on Islamic Unity in Tehran, where hundreds of Muslim scholars and thinkers from around 40 countries gathered under the theme “Islamic Unity in the Thought of the Martyred Imam, Ayatollah Seyyed Ali Khamenei.” 
The conference is focused on strengthening solidarity among Muslims and developing practical approaches to challenges facing Islamic countries.
“The first proposal is a mutual security and non-aggression pact among Muslim countries, under which they commit to respecting one another’s territorial integrity,” Pezeshkian said.
He said Islamic countries should not allow their territory, airspace or facilities to be used to attack another Muslim country, support efforts to divide or destabilize one another, or define their own security at the expense of another country’s security.
Pezeshkian stressed that the proposal did not amount to the creation of a military alliance or require Muslim states to adopt the same foreign policy. Rather, he said, Islamic countries should work together to manage regional security.
His second proposal was the establishment of a permanent mechanism for mediation and conflict prevention in the Muslim world. 
The Organization of Islamic Cooperation, he said, should have the ability to intervene before disputes develop into war rather than simply issue statements after thousands of people have been killed.
His third proposal called for transforming the Muslim world from a collection of separate markets into a network of genuine cooperation, with Muslim scientists working on joint projects and investment from Islamic countries directed toward development and technology within the Muslim world.
Pezeshkian also defended Iran’s

 response to the U.S.-Israeli war of aggression, saying Iran had not initiated the conflict but had stood firmly against aggression.
“Defending Iran does not mean being hostile toward Muslim and neighboring nations,” he said. 
“No Muslim country should allow its territory to be used as a platform for aggression against another Muslim country, and no Muslim country should seek its own security at the expense of its neighbor’s security.”
He said Iran is ready to establish common security arrangements with neighboring countries, emphasizing that Tehran’s approach is based on its experience of war rather than weakness.
The conference also featured warnings that the threat posed by Israel and the United States should not be viewed as limited to Iran.
Seyyed Hassan Khomeini, custodian of Imam Khomeini’s mausoleum, warned that Israel’s threats could extend beyond the current fronts.
“The rulers of the Islamic world think that Trump and Netanyahu are their well-wishers,” he said, warning that if Muslims do not stand against Israel, “tomorrow Lebanon and Syria will not be the only fields of threat, and Saudi Arabia and Türkiye will also be under their bayonets.”
Khomeini urged Muslims to combine resistance to external enemies with solidarity among themselves, saying Muslims should stand against their enemies while resolving their differences with “affection and kindness.”
He also directly appealed to Muslim scholars over the assassination of Ayatollah Khamenei, asking, “Where are the scholars of the Muslim world?” 
He described the martyred Leader as a symbol of confronting hegemony and defending Muslims in Palestine, Lebanon and elsewhere.
Lebanese scholar Sheikh Hassan Baghdadi said Islamic unity has become more urgent amid regional tensions, linking the principle to the Palestinian cause and the resistance against U.S. and Israeli expansionism.
The conference, attended by nearly 600 Iranian and foreign guests, including religious, academic and cultural figures from Iraq, Pakistan, Türkiye, Lebanon, Afghanistan and the Persian Gulf states, is being held during Islamic Unity Week.
Across the discussions, speakers presented Islamic unity not simply as a religious principle but as a practical means of strengthening regional security, resisting external pressure, reducing sectarian divisions and expanding economic, scientific and political cooperation among Muslim countries.
