U.S. President Donald Trump said he will not meet with the representatives of Iran until they change their tune.

The Iranians have no other option but to change before the meeting can become a reality, he said, at the same time expressing hope that U.S. and Iran will have good relations in the future.

 “I’m not meeting with them until they change their tune. It will happen. I believe they have no choice. We look forward to having a great relationship with Iran, but it won’t happen now,” he said.
