US Vice President JD Vance will lead a delegation in talks with Iran in Pakistan beginning on 11 April, according to White House Press Secretary Karoline Leavitt.
In a briefing for reporters, Leavitt said the ceasefire between the US and Iran has created an "opening" that could be the start of a long-lasting peace in the region.
But details on the various peace proposals which will be discussed remain murky, as is the current state of shipping traffic through the strategically vital Strait of Hormuz.
Earlier, Iranian forces warned ships in the area that they would be "destroyed" if they attempted to pass through without permission.
Leavitt, however, said that what Iran is saying publicly is "different privately".
