An Israeli government spokesman says Israel's insistence on maintaining a troop presence in a future Palestinian state can be reviewed over time.
The Israeli demand to remain in the Jordan Valley, a tranquil and largely undeveloped area of the West Bank, is one of the potential obstacles to a Mideast peace deal.
The Palestinians say they cannot accept Israeli forces in their future state. Israel says the move is needed to prevent arms smuggling.
However, government spokesman Mark Regev said Wednesday that such an Israeli presence would not necessarily be permanent.
Regev says the presence could be reviewed and would depend on the Palestinians' ability to keep the peace.
