Trump says anyone trading with Iran will not trade with US as sanctions come into force.

US President Donald Trump has warned that any country trading with Iran will “not be doing business with the United States.” The threat comes as sanctions against the country came into effect at midnight.

The announcement came via the president’s usual medium of communication, Twitter, where Trump announced that the sanctions taking hold were “the most biting ever imposed.”

Trump also promised that Washington will “ratchet up” the economic pressure on the Islamic Republic in November, and said that other nations found to be trading with Iran would not find a trading partner in the United States.

“I am asking for WORLD PEACE, nothing less!,” US president concluded.
