TEHRAN, Sept. 6 (Xinhua) -- Iranian President Hassan Rouhani will not meet U.S. President Donald Trump during the upcoming 73rd United Nations General Assembly, Financial Tribune daily reported Thursday.

Rouhani is scheduled to address the UN conference on Sept. 25, Mahmoud Vaezi, Rouhani's chief of staff, was quoted as saying.

However, Vaezi ruled out the possibility of a meeting between Rouhani and Trump on the sidelines of the UN conference despite Trump's readiness for such meeting.

A day earlier, Trump said it is possible for him to meet with Rouhani at the United Nations.

The UN General Assembly comes amid heightened tensions between Iran and the United States, which pulled out from the landmark 2015 Iranian nuclear deal in May and re-imposed sanctions on the Islamic republic.
