US President Joe Biden will not come up with a plan to restart the stalled Israel-Palestinian peace process when he visits the West Bank today, at the end of the first leg of his Middle East trip, a senior administration official said.

Biden will restate his backing for a two-state solution to the decades-long conflict and will unveil a fresh package of economic and technical assistance for the Palestinians, but there are no expectations of any major political breakthrough.

"[There] are practical realities on the ground that we are very mindful of so we have not come in with a top-down plan but we have always said that if the parties are ready to talk, and we think they should, we will be there, right beside them," the official said.

Biden is expected to meet Palestinian President Mahmoud Abbas in Bethlehem before leaving for Saudi Arabia on the second stage of his trip.

Even before his visit, Palestinian leaders had accused Biden's administration of prioritising Israel's integration into a regional security arrangement with Arab countries above their concerns, including self-determination and continued Israeli settlement building in the occupied West Bank.

Yesterday, as Biden and Israeli Prime Minister Yair Lapid announced deepening security ties in their so-called "Jerusalem Declaration", there were protests in the West Bank and Gaza against his visit.

Biden administration officials have rejected Palestinian charges of inaction, pointing to a reversal of the funding cuts and diplomatic freeze imposed by former president Donald Trump.

"There was really no connection whatsoever, no discussions with the Palestinians, funding had been entirely severed, there was really no prospect of any political discussions of any kind," the official said.

He said the move to deepen Israel's regional integration "is not ... an end run around that fundamental issue".

With little prospect of political progress, the focus is likely to be on the new funding and technical assistance measures Biden will unveil.

As well as a multi-year contribution of up to US$100 million for hospitals in East Jerusalem, he will announce measures to upgrade telecoms networks in the West Bank and Gaza to high-speed 4G standards by the end of 2023 and other measures to ease travel between the West Bank and neighbouring Jordan.

In addition, there will be a separate US$201 million funding package provided through the UN relief agency UNRWA to help Palestinian refugees.

A two-state solution with an independent Palestinian state sitting alongside the existing state of Israel has long been the favoured solution for the international community. But it has appeared an increasingly distant prospect, with hardening attitudes and waning support on both sides.

Yesterday, both Biden and Lapid voiced support for the two-state model. But with Israel heading for elections in November and little backing for stopping the expansion of Israeli settlements on West Bank land that Palestinians want for a future state, immediate prospects for agreement appear remote.
