Iran’s president cautioned North Korea not to trust President Trump during negotiations with the United States over its nuclear weapons arsenal, according to a report Thursday.

“The U.S. administration performance in these years has led the country to be considered untrustworthy and unreliable around the world which does not meet any of its obligations,” Hassan Rouhani told North Korea’s foreign minister, Reuters reported, citing Iranian state media.

“In the current situation, friendly countries should develop their relations and cooperation in (the) international community,” he told Ri Yong Ho, adding the two countries have “always had close views.”

Iran rejected US calls for talks earlier this week after Trump reimposed sanctions against the Islamic Republic following his withdrawal from a 2015 deal brokered by former President Barack Obama and several world powers to curb Iran’s nuclear program.

Ri arrived in Tehran after reportedly sparring with Secretary of State Mike Pompeo during a summit of Asian nations in Singapore over the weekend.

Trump and North Korean leader Kim Jong Un agreed during a June meeting to denuclearize the peninsula, but officials from the two countries have been squabbling over the terms since then.

North Korea’s foreign ministry complained Thursday that the regime had quit conducting nuclear tests, stopped firing missiles and dismantled a “nuclear test ground,” but the US continues to insist on “denuclearization first.”

Ri told Rouhani that Trump’s pulling out of the pact and reimposing sanctions was an “action against international rules and regulations,” Iranian media reported, according to Reuters.

“North Korea’s strategic policy is to deepen relations with the Islamic Republic of Iran and confront unilateralism,” Ri said.
