U.S. President Donald Trump's economic vision as part of the wider plan to resolve the Israeli-Palestinian conflict has been met with contempt, repudiation and exasperation in the Arab world, even as some in the Persian Gulf called for it to be given a chance.

The $50 billion "peace to prosperity" plan, set to be presented by Jared Kushner, Trump's son-in-law, at a conference in Bahrain this week, envisions a global investment fund to lift the Palestinian and neighboring Arab state economies.

The White House on Saturday outlined the plan, which includes 179 infrastructure and business projects and would fund a $5 billion transportation corridor to connect the West Bank and Gaza Strip.
