Asia-Pacific markets were set to open higher after President Donald Trump said he agreed to suspend planned attacks on Iranian infrastructure for two weeks.

Trump renewed threat to target Iran's civilian infrastructure if a peace deal is not reached in less than 24 hours, while signaling Iranian leadership is negotiating in earnest.

Earlier, U.S. stocks swung sharply during regular trading as uncertainty about the war with Iran increased after Trump had threatened that a “whole civilization will die tonight."
