NEW YORK (Reuters) - A U.S. push to change the Iran nuclear deal was sending a "very dangerous message" that countries should never negotiate with Washington, Iran's foreign minister warned as U.S. and North Korean leaders prepare to meet for denuclearisation talks.

Speaking to reporters in New York on Saturday, Mohammad Javad Zarif also said that for French President Emmanuel Macron and German Chancellor Angela Merkel "to try to appease the president (Donald Trump) would be an exercise in futility."
