Iran has continued exchanging messages with the United States, but the conditions for negotiations do not currently exist because Washington has undermined diplomacy through its military actions, Foreign Ministry spokesman Esmaeil Baqaei said.
In an interview with Austria's ORF television, Baqaei said Iran's immediate priority is defending its sovereignty rather than engaging in negotiations.
"We are exchanging messages, but our priority now is defending Iran's sovereignty, territorial integrity and people," he said.
Baqaei accused Washington of repeatedly undermining diplomacy, saying US actions had destroyed the conditions necessary for negotiations and violated previous understandings with Tehran.
He described recent US strikes as a continuation of an "illegal war" against Iran, arguing that they reflected Washington's failure to honour its commitments.
Regional tensions
On the Strait of Hormuz, Baqaei said Iran had fulfilled its responsibility to ensure the security of international shipping but would not allow the strategic waterway to become a platform for threatening the country's national security.
He also blamed the US and Israel for escalating tensions in the region, saying their military actions had destabilised the security situation.
Turning to the 2015 nuclear deal, Baqaei said European countries had failed to honour their commitments following the US withdrawal from the agreement, adding that they "owe Iran a great debt" for abandoning their obligations.
Tensions between the US and Iran have intensified in recent weeks, with the US carrying out attacks on Iran and Tehran responding by targeting US military facilities and equipment in countries across the region, including Bahrain, Jordan and Kuwait.
On July 8, US President Donald Trump declared a memorandum of understanding with Iran "over", accusing Tehran of violating the agreement.
The announcement followed attacks on three tankers in the Strait of Hormuz and renewed disagreements over navigation rules in the strategic waterway.
Washington has called for unrestricted passage through the Strait of Hormuz, while Tehran insists vessels transit through a channel near its coastline under a navigation mechanism administered by Iran.
Axios reported on Saturday, citing sources familiar with the decision, that Trump has directed the US military not to launch new strikes on Iran, ending nearly two weeks of daily attacks.
