TEHRAN, May 31 (Xinhua) -- Iranian Parliament Speaker Mohammad Baqer Qalibaf said Sunday that Tehran will not agree to any deal with the United States until the rights of the Iranian people have been secured.

Addressing an online parliament session, Qalibaf stressed that Iranian negotiators have no trust in the "enemy's" words and promises, according to the official news agency IRNA.

"Our criterion is tangible achievements that we must attain in order to fulfill our commitments in return," he said. "We will not approve any agreement until we are sure that we have secured the Iranian nation's rights."

The speaker noted Iran's "achievement" on the battlefield, stressing that the diplomacy's job is to transform "these victories into political and legal achievements."

He warned that in a new phase of war, the "enemies" seek to sow internal discord through economic pressure and media propaganda to force Iran to surrender, and expressed confidence that Iran's people would resist them.

In a Friday post on social media platform X, Qalibaf, who serves as Tehran's top negotiator in peace talks with Washington, said, "We obtain concessions not through dialogue, but with missiles; in negotiations we merely make them understandable."

Separately, Iran's Islamic Revolution Guard Corps (IRGC) said on Sunday that 28 ships, including oil tankers, container vessels, and commercial ships, passed through the Strait of Hormuz within the past 24 hours after obtaining permission and receiving protection from its Navy.

Iran had tightened control over the strait since Feb. 28, when it barred passage to vessels belonging to or affiliated with Israel and the United States after the two countries' joint strikes on Iranian territory. The United States later imposed its own blockade on the waterway after peace negotiations with Iran in Pakistan's Islamabad collapsed.

Over the past weeks, Iran and the United States are reportedly exchanged several proposed plans outlining conditions for peace through Pakistan's mediation, and are working to finalize a memorandum of understanding to end the war.
