Iranian Ayatollah Ali Khamenei called the United States an untrustworthy and warmongering country on Wednesday, and urged neighboring Armenia to expand ties with Tehran despite American pressures.

Iran is struggling with the sanctions imposed by Washington after US President Donald Trump pulled out of a 2015 nuclear deal between Iran and six major powers last year, calling it deeply flawed.

Washington has told international firms that they will be barred from the US financial system if they breach its sanctions on Iranian energy and banking sectors. The warning has made many countries wary of doing business with Iran.

“Americans are totally untrustworthy and they want sedition, corruption, disagreement and war everywhere. They are against Iran-Armenia relations,” Khamenei’s official website quoted him as saying during a meeting with Armenian Prime Minister Nikol Pashinyan in Tehran.

“We are committed to good relations with our neighbors, but US officials like (national security adviser) John Bolton have no understanding of human issues and relations,” Khamenei charged. Bolton takes a particularly hawkish view of Iran in the Trump administration.

President Hassan Rouhani said earlier that Iran was ready to export more gas to Armenia.

Iran has accused the United States of starting an “economic war” against it, saying the sanctions are preventing Iranians’ access to vital resources. The US Treasury says imports of medicines and food are exempted from sanctions.
