Iranian Foreign Minister Abbas Araghchi warned of a "new conspiracy" being planned by Tehran's opponents, warning that they may seek to create economic and social unrest to destabilize the country.
Speaking at a forum in Isfahan, he explained that the conspiracy will not be based on a direct military confrontation, but an attempt to stir economic problems and weaken Iran internally.
Such a conspiracy will fail, he declared.
On Israel's 12-day war against Iran in June, Araghchi stressed that Tehran's "perseverance thwarted the enemy conspiracy that sought Iran's surrender."
He described the war as a "feat of historic resistance."
"Iran's enemies believed they could impose unconditional surrender within days, but they realized that they needed to retreat against the perseverance of the society and armed forces," added the FM.
The war "sent a message that the Iranian people will not succumb to oppression or dictates," he declared.
Israel killed dozens of Iranian commanders, officials and scientists tied to Iran's nuclear program during the June war. The US briefly joined the conflict to strike Iran's nuclear facilities.
On sanctions, Araghchi said: "We have to acknowledge that we have to live with them."
He stressed that he was aware of their impact and cost, but they also reveal opportunities to introduce reforms.
Moreover, he said sanctions are often used as a form of psychological warfare with the aim to destabilize the economy.
He vowed that the Foreign Ministry will maintain diplomatic efforts to lift the sanctions.
"It will not spare an effort" in investing in any opportunity to ease the international pressure, he added.
Netanyahu's meeting with Trump
Meanwhile, attention turns to Israeli Prime Minister Benjamin Netanyahu's meeting with US President Donald Trump on Monday.
Washington has maintained its "maximum pressure" policy against Iran, while Israel has warned that Tehran was rebuilding its military capabilities after the war during which it dealt it heavy blows to its ballistic missile arsenal.
Araghchi said last week that Iran was not ruling out a new Israeli attack, "but it was prepared more than before."
Media reports have said that Netanyahu will discuss with Trump Iran's ballistic missile program.
Earlier, this week, he warned that Israel was aware of military drills Iran had recently carried out.
Israel is monitoring the situation and will respond firmly to any attack, he stressed without elaborating.
