Any temporary peace agreement between the United States and Iran must be followed by deeper talks about Tehran’s nuclear stockpiles, missiles, and other critical issues, European Union foreign policy chief Kaja Kallas said.Speaking at a news conference in Islamabad on June 1, Kallas, the EU high representative for foreign affairs and security policy, said she sees a "tenuous diplomatic opening" to extend the current temporary cease-fire and reopen the Strait of Hormuz despite an exchange of attacks overnight by both Iran and the United States."Any temporary understanding between the US and Iran must be followed by deeper talks about Tehran's nuclear stockpile and other critical issues," the bloc's top diplomat told a joint news conference with Pakistani Deputy Prime Minister and Foreign Minister Ishaq Dar.

Kallas praised Pakistan's role as a mediator in the Gulf crisis and expressed the EU’s readiness to contribute to the peaceful resolution of the US-Iran dispute mentioning the group’s “economic leverage, hard-won nuclear expertise, longstanding relationships with partners across the Gulf, and direct engagement with Iran itself.”“I see a concrete role for the EU in helping to make any eventual agreement durable -- whether through maritime operations or economic incentives that support long-term stability,” she said suggesting “strict conditions” for a “calibrated path towards sanctions relief” for Iran.The US and Israel launched air strikes against Iran on February 28 following their continued disagreement over issues relating to Iran’s nuclear capability.
