This was announced by Oman, where the meeting was scheduled to take place on Monday.
The meeting is postponed "to create fruitful conditions for a constructive dialogue," the country's national news agency writes.
The announcement comes after Bahrain said on Saturday that the country would not attend the planned meeting.
Strained relationships
When Iran presented plans for the meeting, it said that Iraq and the coastal states of the Persian Gulf would participate. The purpose of the meeting would be “to promote better understanding between the countries of the region and contribute to strengthening common regional security,” according to the country's Foreign Ministry.
Trade through the Strait of Hormuz has been severely restricted since the US and Israel attacked Iran in February of this year, triggering a wider conflict in the region. Iran is blocking the strait and the US Navy is blocking Iranian maritime traffic in the area.
The relationship between Iran and several US-allied countries in the region has been strained since Iran, in response to US attacks, attacked American targets in those countries.
“Turning the page”
However, a rapprochement with the United Arab Emirates, which announced in August that it was halting all trade with Iran, appears to be underway.
"For the first time since the outbreak of the war and the incidents that took place in the Persian Gulf, we have had a constructive exchange of views with the Crown Prince of Abu Dhabi," Iranian President Masoud Pezeshkian said earlier on Sunday.
The statement comes a day after Pezeshkian's meeting with Crown Prince Sheikh Khaled in connection with the BRIC summit in India.
It was decided that we should turn around, look to the future and build it together, says Pezeshkian.
