Iran’s Foreign Minister Abbas Araghchi met with a Pakistani delegation led by army chief Asim Munir in Tehran on Wednesday, as regional efforts continue to facilitate dialogue between Iran and the United States.

Iranian state media reported that the visiting delegation was expected to convey a message from Washington and discuss arrangements for a possible second round of talks between the two sides.

According to reports, Munir arrived in Tehran earlier in the day leading a high-level delegation, with discussions focusing on recent diplomatic developments and ongoing mediation efforts.

The visit follows earlier talks in Islamabad that ended without a breakthrough, though officials have indicated that both Washington and Tehran have agreed in principle to continue negotiations.

Regional mediators are working to sustain momentum toward renewed dialogue, but progress has remained slow amid broader geopolitical tensions.

The meeting in Tehran underscores Pakistan’s emerging role as an intermediary in efforts to revive negotiations and ease tensions between Iran and the United States.

The strategic Strait of Hormuz has emerged as the focal point of rising tensions in the Middle East, as the United States enforces a blockade on Iranian ports and Tehran signals possible retaliation, even while tentative diplomatic efforts show signs of life.

The narrow waterway — through which roughly a fifth of the world’s oil supply passes in normal times — has become a flashpoint in the seven-week conflict, with maritime traffic severely curtailed and global markets rattled.

The U.S. military said its blockade is now fully operational, with United States Central Command confirming that no vessels crossed the blockade in the first 24 hours. Several ships were forced to turn back, underscoring Washington’s tightening grip on shipping routes linked to Iran.

The move is designed to cut off Iran’s oil exports, a vital economic lifeline. However, it has also deepened fears of disruption in the Strait of Hormuz, where even limited interference can send shockwaves through global energy markets, AP reported.

Shipping disruption drives economic fears

Since the conflict began, Iran has effectively restricted access to the strait, prompting many commercial vessels to avoid the route altogether. Tankers have reversed course or delayed transit, creating a bottleneck in one of the world’s most critical energy corridors.

The result has been a surge in oil prices in recent weeks, with knock-on effects on fuel, food and shipping costs worldwide. Although prices eased slightly on renewed hopes for diplomacy, uncertainty around the waterway continues to weigh heavily on the global economy.

Diplomatic efforts continue amid military standoff

U.S. President Donald Trump said a second round of talks with Iran could take place within days, possibly in Islamabad, following an initial round that failed to produce an agreement.

António Guterres has urged a return to negotiations, alongside maintaining a ceasefire and ensuring freedom of navigation through the Strait of Hormuz — a principle increasingly under strain.

Despite the diplomatic push, no formal talks have been scheduled, and tensions remain high as both sides continue to test each other’s resolve in and around the waterway.

Wider regional impact

The confrontation over Hormuz comes against the backdrop of a broader regional conflict involving Israel and Iran-backed groups, which has already caused widespread destruction and displacement, particularly in Lebanon.

While separate diplomatic efforts between Israeli and Lebanese officials have been described as constructive, the risk of escalation tied to the Strait of Hormuz remains the most immediate global concern.

A fragile balance

With the blockade in force and Iran warning of retaliation, the Strait of Hormuz has become both a pressure point and a bargaining chip. Any escalation in the narrow passage risks not only reigniting open conflict but also triggering a wider economic shock.

U.S. Central Command said it will begin implementing ​a blockade of all maritime ‌traffic entering and exiting Iranian ports on April 13 at 10 ​a.m. ET (1400 GMT), after ​President Donald Trump said the U.S. ⁠Navy would start blockading ​the Strait of Hormuz.

“The blockade ​will be enforced impartially against vessels of all nations entering or departing Iranian ​ports and coastal areas, ​including all Iranian ports on the Arabian ‌Gulf ⁠and Gulf of Oman. CENTCOM forces will not impede freedom of navigation for vessels transiting ​the Strait ​of ⁠Hormuz to and from non-Iranian ports,” CENTCOM wrote ​in a statement on ​social ⁠media.

Additional information will be provided to commercial mariners through a ⁠formal ​notice before the ​blockade starts, CENTCOM added.
