TEHRAN, Sept. 18 (Xinhua) -- Iranian President Hassan Rouhani said here Wednesday that Washington should give up "maximum pressure campaign" against the Islamic republic.

"Negotiations under maximum pressure is impossible," Rouhani was quoted as saying by official IRNA news agency.

"If the Americans want talks, they should stop all pressures" against Iran, Rouhani said in a cabinet meeting on Wednesday.

On Tuesday, Iran's Supreme Leader Ayatollah Ali Khamenei said that Iranian officials unanimously rule out talks with the United States at any level.

"Through negotiations, they (the Americans) are seeking to impose their demands on Iran and prove the effectiveness of 'maximum pressure campaign'," Khamenei said.

U.S. President Donald Trump withdrew the United States from the 2015 Iran nuclear deal in May 2018 under the pretext that the deal was not comprehensive, saying it did not address the development of Iran's ballistic missile projects.

Subsequently, the U.S. administration launched a "maximum pressure campaign" and reinstated sanctions on Iran's economy, mainly on Iran's oil exports.
