Ahead of the United States’ newest round of sanctions targeting his country, Iranian President Hassan Rouhani on Sunday accused the Trump administration of “psychological and economic warfare” and of working toward regime change in Iran.

Speaking at Tehran University, Rouhani expressed outrage amid rising tensions following President Donald Trump’s breach of the 2015 nuclear deal between Iran, the U.S., and five other countries as well as the European Union.

“In the past 40 years, there has not been a more spiteful team than the current U.S. government team toward Iran, Iranians and the Islamic Republic,” Rouhani said.

After announcing the United States’ withdrawal from the Joint Comprehensive Plan of Action (JCPOA) in May—against the advice of several world leaders and the wishes of 63 percent of the American public—Trump reimposed sanctions on Iran, banning the country’s purchasing of U.S. banknotes and precious metals as well as airplane and auto parts.

The effects of the sanctions have already been felt by Iranians, with the prices of cars, electronics, and medications doubling.

Earlier this month, the International Court of Justice (ICJ) of the United Nations ordered the U.S. to ensure its sanctions do not endanger Iranians by affecting the delivery of humanitarian aid.
