Tehran, Iran (CNN) Iran's Foreign Minister, Mohammad Javad Zarif, has said his country won't negotiate with President Donald Trump unless the US shows Tehran "respect" by honoring its commitments under the disputed nuclear deal.

In an exclusive interview with CNN, Zarif warned the US was "playing a very, very dangerous game" by boosting its military presence in the region.

Zarif criticized the US for sending the USS Abraham Lincoln carrier strike group and a bomber task force to the Gulf. "Having all these military assets in a small area is in of itself prone to accidents," Zarif said. "Extreme prudence is required and the United States is playing a very, very dangerous game."

He accused Washington of walking out first on the Joint Comprehensive Plan of Action, or JCPOA, the 2015 deal designed to limit Iran's nuclear capabilities in return for the lifting of sanctions. "We acted in good faith," Zarif said of the deal, which was signed by the US, Iran, Britain, China, France, Germany and Russia. "We are not willing to talk to people who have broken their promises."
