Vice President JD Vance has paused a scheduled trip to Pakistan as the Trump administration reassesses prospects for negotiations with Iran aimed at stabilizing ongoing tensions, according to multiple people familiar with the matter cited by The Wall Street Journal.

The trip, which was expected to include discussions in Islamabad tied to efforts to advance talks with Tehran, was delayed following internal White House meetings reviewing the status of diplomacy. Officials are now uncertain whether the negotiations will proceed as planned, given Iran’s reluctance to confirm participation.

According to the Journal’s reporting, the pause reflects growing concern within the administration that Iran has not agreed to meet U.S. conditions related to nuclear enrichment and broader regional security demands. One source indicated that former President Donald Trump is also weighing whether to cancel the trip entirely.

Vance could still depart later in the week, possibly on short notice, depending on developments, according to individuals familiar with the planning.

Iranian officials have reportedly linked their participation in any talks to disputes over recent U.S. maritime enforcement actions in the Strait of Hormuz. Tehran has accused the United States of violating a ceasefire and has characterized the naval blockade of Iranian ports as an “act of war,” according to Reuters reporting.

The Iranian government has not formally committed to attending negotiations in Islamabad, and its position remains conditional on the resolution of those maritime disputes, according to international reports.

The White House has not publicly commented on the status of the vice president’s travel plans.

The uncertainty comes as a ceasefire deadline approaches later this week, raising questions about whether diplomatic engagement will proceed or further escalate amid already heightened tensions in the region.
