Trump enacted new sanctions Monday targeting Iran's Supreme Leader Ayatollah Ali Khamenei. U.S. officials also say they plan sanctions against Iranian Foreign Minister Mohammad Javad Zarif.
The already strained US-Iran relationship has further deteriorated after IRGC on Thursday downed American unmanned drone RQ-4, Global Hawk after it violated Iranian airspace.
Iran's mission to the United Nations did not immediately respond to a request for comment.
Trump said that the Iranian economy is in a mess.
In addition to India, Special Representative for Iran Brian Hook will be travelling to Europe to further discuss US foreign policy toward Iran.
There has been widespread speculation over whether Iran would be forced back to the negotiating table following Washington's withdrawal from the 2015 nuclear deal and reimposition of sanctions.
