Iran on Friday said it is working together with the Indian government to keep its oil export lines to India open even after US sanctions on the Gulf nation kick in on November 4 following Washington's withdrawal from the Iran nuclear deal.

India and the US on Thursday signed a long-negotiated defence pact that enables Indian armed forces to buy more sensitive military equipment from Washington but there was no progress on securing a waiver from American sanctions that bar New Delhi from purchasing Russian weapons or Iranian oil.

US President Donald Trump has said it is possible for him to meet his Iranian counterpart Hassan Rouhani at the UN. Speaking on Wednesday before a bilateral meeting with Kuwait's visiting Amir Sheikh Sabah Al-Ahmed Al-Jaber Al-Sabah, Trump said "anything is possible" regarding the meeting, Xinhua reported. "Whether they want to talk or not, that's up to them, not up to me," he said. "I will always be available... we'll see what happens." Trump said on July 30 that he is ready to meet with Rouhani without preconditions. "I'd meet with anybody. I believe in meeting," Trump said. "They want to meet, I'll meet. Any time they want. Good for the country. Good for them. Good for us. And good for the world." However, the US in August re-imposed sanctions on Iran that had been suspended under a landmark 2015 nuclear deal. Rouhani said in response that the Iranians would make the US "regretful" for its renewal of sanctions. He also said that the US administration "is not trustworthy for any negotiations" after its withdrawal from the Iranian nuclear deal, since "negotiations with sanctions don't make sense". Iranian Supreme Leader Ayatollah Ali Khamenei also said lately that any negotiation with the US to solve the existing problems is an "obvious mistake". US-Iranian relations have been at odds as the Trump administration left the historic Iran nuclear deal, de-legitimised its government, vowed to re-impose sanctions on the nation and pressed other nations to cut down their purchase of Iranian oil to zero.

Lack of efforts by Europe to save the 2015 Iranian nuclear deal will have "serious consequences," Kamal Kharrazi, chief of Iran's Strategic Council on Foreign Relations, said on Sunday, according to Tehran Times daily.

Pakistan on Friday expressed its support to Iran on the international nuclear deal related to the Iranian nuclear issue during talks between foreign ministers of the two countries, the Foreign Ministry said.

Iran's Supreme Leader Ayatollah Ali Khamenei on Wednesday warned that Iran will quit the 2015 Iranian nuclear deal if the interests of his country are not secured.
