US President Donald Trump’s Middle East envoy lashed out at the Palestinian Authority (PA) on Friday over its refusal to take part in next week’s American-organized conference in Manama on investment in the Palestinian economy.

“The PA is calling for demonstrations against the Bahrain workshop,” Jason Greenblatt tweeted. “Tells you everything you need to know about their priorities & intentions. Their leadership is happy w/ the status quo & would rather Palestinians suffer than at least explore a different path for a better future.”

The “Peace to Prosperity” summit is set to take place next Tuesday and Wednesday, June 25-26. The event is supposed to mark the kick-off of the Trump administration’s long-awaited Israeli-Palestinian peace initiative, spearheaded by the president’s son-in-law and senior adviser, Jared Kushner.
