Plans for a second round of direct peace talks between the United States and Iran in Islamabad have been thrown into uncertainty after Iran reimposed restrictions and effectively closed the Strait of Hormuz, accusing Washington of violating the fragile ceasefire through its naval blockade of Iranian ports.
Pakistan, which successfully mediated the first round of historic face-to-face negotiations earlier this month, is actively pushing for the next round. However, the latest escalation in the Strait of Hormuz has complicated efforts, with both sides trading blame and diplomats warning that momentum is rapidly fading.
The first round of talks, held on April 11-12 in Islamabad, lasted over 21 hours but ended without a comprehensive agreement. Major sticking points included Iran’s nuclear program, regional proxies, and control of the Strait of Hormuz. Despite the deadlock, both sides left the door open for further dialogue, with Pakistan continuing behind-the-scenes efforts to arrange a follow-up meeting.
Hormuz Crisis Derails Momentum
Just days after a brief reopening, Iran announced on April 18 that it was once again asserting “strict control” over the strategic waterway, through which nearly 20% of global oil passes. Iranian officials cited repeated US violations, including the ongoing naval blockade of Iranian ports and alleged aggressive maneuvers by American warships. Reports also emerged of Iranian gunboats firing on commercial vessels attempting to transit the strait.
Iranian Foreign Ministry sources stated that the closure will remain in effect until the United States lifts its blockade and demonstrates good faith ahead of any new talks.
U.S. officials, including President Trump, have downplayed the Iranian move while maintaining that the blockade is necessary pressure to secure a strong deal. White House spokespeople indicated that a second round in Islamabad remains “very likely,” but no firm date has been set.
Pakistan’s Mediation Role
Pakistani officials have increased security preparations in Islamabad and Rawalpindi in anticipation of renewed high-level talks.
Analysts warn that the re-closure of the Strait of Hormuz has raised global oil prices and increased the risk of miscalculation, making the second round more urgent — yet harder to organize. European allies and the United Nations have called for immediate de-escalation.
As the two-week ceasefire approaches its expiry, the coming days will be critical. Whether the second round of Islamabad talks can proceed depends on whether Washington and Tehran can bridge the gap created by the Hormuz crisis and mutual accusations of violations.
