The four-day trip, President Donald Trump’s first overseas tour since his reelection, is expected to focus on business deals and investments from the region.

President Donald Trump kicked off his trip to the Gulf with a surprise announcement that the United States will lift long-standing sanctions on Syria, and a $600 billion commitment from Saudi Arabia to invest in the US.

The United States is to lift all sanctions on Syria, Donald Trump announced on Tuesday. The removal of sanctions, at the behest of Crown Prince Mohammed bin Salman of Saudi Arabia, represents a major US policy shift before an expected meeting between Mr Trump and Ahmed al-Sharaa, the Islamist president of Syria, on Wednesday.
