Omani Foreign Minister Badr al-Busaidi has called on the six Gulf countries, Saudi Arabia, Bahrain, Kuwait, Qatar, the UAE, and Oman, as well as Iraq and Iran, to unite under a single "non-aggression" security pact.

Speaking at the UK's Cambridge University on Monday during a diplomatic visit, Busaidi said it was time for the Gulf "to step up and take responsibility for our own security" and end reliance on "external powers".

"The nuclear issue and the Hormuz issue are both impossible to resolve because external powers continue to define the terms of engagement, while regional powers are unable to take collective responsibility for making their own security arrangements and reach a consensus on them," Busaidi said.

"That is why in my talk today I am making a call for us in the Gulf to step up and take responsibility for our own security, and for us to do so inclusively." 

His speech came amid a flurry of diplomatic activity surrounding Iran, including senior officials from the Mecca Defence Alliance meeting Iranian leaders in Tehran on Monday.

Iran's top security official, Mohsen Rezaei, said the talks showed that US threats had little impact on regional diplomacy and marked the start of a "real transformation".

Members of the alliance - Saudi Arabia, Turkey, and Pakistan - gathered to negotiate as regional powers strive to end the Israeli-US war against Iran and establish a security framework independent of Washington.

The talks come as the conflict continues to threaten the region and the global economy, amid mounting fears of renewed US-Israeli attacks.

'False perception' of antagonism against Iran

Busaidi said that positioning Iran as the security threat has been "the most damaging of the priorities imposed on the region from the outside".

"This produced an unstable regional system constructed on the entirely false perception that there is a fundamental regional antagonism between Iran and the Arab states of the Gulf," he said.
