Asian markets slipped today after President Donald Trump said the United States would begin imposing unilateral tariffs within two weeks, reigniting trade war fears just days after reaching a framework deal with China.

The announcement reversed investor optimism sparked by earlier progress in London talks and revived concerns of global economic disruption.

President Trump indicated that governments would soon receive letters outlining Washington’s tariff terms, which they could take or leave, raising fresh doubts about the stability of his trade policy.

The market unease was further heightened by president Trump statement that U.S. personnel were being withdrawn from the Middle East due to rising tensions with Iran, where nuclear talks have stalled.

He said the region had become increasingly dangerous and stressed that Iran would not be allowed to acquire a nuclear weapon.
