Iran’s U.N. mission said it would be willing to discuss its nuclear program if talks were restricted to military concerns, after its supreme leader appeared to reject President Trump’s offer to start discussions.

Iran’s Supreme Leader Ayatollah Ali Khamenei has said calls for negotiations by “bully states” are aimed at dominating others, not resolving issues, after US President Donald Trump urged him to reach a nuclear deal.

Iran says it would consider negotiations with the United States if talks were confined to concerns about the militarization of the country’s nuclear program.

Ayatollah Ali Khamenei decried “bullying governments” in an apparent response to a letter the White House sent to Iran earlier in the week.

President Trump said he sent a letter to Iran's Supreme Leader Ayatollah Ali Khamenei last week asking that the two leaders "negotiate" over the Islamic republic's nuclear program. On Saturday, the Iranian leader condemned the effort by unnamed "bullying governments" to make a deal over the program.

Iran’s Supreme Leader Ayatollah Ali Khamenei says he rejects a U.S. push for talks between the two countries because they would be aimed at imposing restrictions on Iranian missile range and its regional influence.

The Kremlin, asked on Monday if Russia had held consultations with Iran before or after Tehran responded to a letter from U.S. President Donald Trump urging the country to negotiate a nuclear deal, said Iran formulates its own policy positions.

Supreme Leader Ayatollah Ali Khamenei said Iran will not be bullied into negotiations, a day after President Donald Trump said he sent a letter urging Tehran to negotiate.

Trump said on Friday he had warned Tehran in a letter it could face military action unless it agreed to talks for a nuclear deal. In a furious response on Saturday, Ayatollah Ali Khamenei said Iran would not negotiate with "bullying governments" insisting on talks.
