(CNN) White House senior adviser Jared Kushner is meeting with top foreign officials this week in Morocco, Jordan and Israel before he unveils the economic portion of his long-awaited Israeli-Palestinian peace plan during a conference next month, a White House official and administration official said.

Traveling alongside Special Representative for International Negotiations Jason Greenblatt and the US Special Representative for Iran Brian Hook, Kushner will also meet with officials in Montreux, Switzerland, and in London, where President Donald Trump will arrive for a state visit next week.

Kushner and the peace team will focus on shoring up support for the economic portion of the peace plan, which seeks a multi-billion dollar investment in the region to spur the Palestinian and surrounding economies should a peace agreement be reached, an administration official said. Kushner made a similar trip to the Middle East earlier this spring with the same goal.

The US officials do not plan on sharing details of the political portion of the plan during the trip, the administration official said, but they will listen to input from the foreign officials on those thornier issues.

Trump administration officials have offered almost no details about the political portion of the plan, which Kushner has called "in-depth operational document" and Trump has deemed the "deal of the century." US officials hope to drum up interest in their effort by focusing on the potential economic benefits of their peace plan before they address the most contentious issues like Palestinian statehood and the status of Jerusalem.
