The candidates former Chilean president Michelle Bachelet, International Atomic Energy Agency chief Rafael Grossi of Argentina, UN trade and development head Rebeca Grynspan of Costa Rica, and former Senegalese president Macky Sall are set to participate in hours-long hearings on Tuesday and Wednesday in a process aimed at increasing transparency in the selection of the UN’s top official.

The public dialogues, introduced in 2016, allow member states and non-governmental organizations to question candidates directly. However, the final decision will rest with the 15-member UN Security Council, where the five permanent members the United States, Russia, China, Britain and France hold veto power.

The selection comes at a time when the United Nations faces significant operational strain, including what officials describe as a severe budget shortfall linked to delayed or withheld contributions, particularly from the United States. Washington’s envoy to the UN has indicated that the next secretary-general must align with U.S. priorities, underscoring the geopolitical stakes involved in the appointment.

Bachelet, 74, brings decades of political and diplomatic experience, having served as Chile’s first female president and later as the UN High Commissioner for Human Rights. Her tenure at the rights body drew criticism from some member states, including China, following reports addressing alleged abuses against Uyghur populations.

Grossi, 65, has led the IAEA since 2019 and has played a central role in navigating nuclear-related tensions involving Iran and the conflict in Ukraine, including concerns surrounding the Zaporizhzhia nuclear facility. His candidacy places him under scrutiny from both Western powers and Russia, reflecting the sensitivity of his portfolio.

Grynspan, 70, currently heads the UN Conference on Trade and Development and has been credited with facilitating the Black Sea Grain Initiative, which enabled grain exports amid the Ukraine conflict.

She has emphasized multilateral cooperation and her personal background as the daughter of Holocaust survivors in articulating her commitment to the UN Charter.Sall, 64, stands as the only candidate outside Latin America, a region many member states argue should produce the next secretary-general under informal rotation practices.

His candidacy has faced resistance within Africa, including from segments of the African Union, and criticism related to his handling of political unrest during his presidency.All four candidates have pledged to restore confidence in the United Nations and address divisions among member states, as conflicts and economic pressures test the institution’s capacity to respond effectively.

The hearings are expected to shape diplomatic negotiations in the coming months as Security Council members weigh competing priorities before recommending a candidate to the General Assembly.

Speaking at a Turning Point USA event, Vance said distrust between Washington and Tehran remains a fundamental obstacle to any durable agreement. “There is a lot of, of course, mistrust between Iran and the United States of America.

You are not going to solve that problem overnight,” he said, while adding that Iranian negotiators appeared willing to reach a deal.Vance, who participated in recent negotiations held in Pakistan, said he was cautiously optimistic about the trajectory of talks.

“I feel very good about where we are,” he said, signaling confidence in ongoing diplomatic efforts despite recent setbacks.Donald Trump said on Tuesday that discussions aimed at ending the Iran war could resume in Pakistan within days, following the collapse of negotiations over the weekend.

The breakdown prompted Washington to impose a blockade on Iranian ports, escalating economic and military pressure on Tehran.A two-week ceasefire between US and Iranian forces remains in effect, with one week remaining, offering a limited window for diplomatic engagement.

The pause in hostilities follows weeks of intensified conflict that began on February 28, when US and Israeli forces launched strikes on Iran.Tehran retaliated with attacks targeting Israel and Gulf states hosting US military bases, expanding the geographic scope of the conflict.

Subsequent US-Israeli operations inside Iran, along with Israeli strikes in Lebanon, have resulted in significant casualties and widespread displacement, according to official accounts.

The evolving situation underscores the complexity of negotiations, with diplomatic momentum constrained by entrenched mistrust and ongoing military developments.

Two Pakistani officials, speaking on condition of anonymity, said Islamabad has offered to again facilitate negotiations, although the final venue would depend on whether Washington or Tehran request an alternative location.

They described the initial round of talks as part of an ongoing diplomatic process rather than a one-off effort.The proposal follows marathon negotiations held on April 12 that ended without a breakthrough but were marked by what U.S. Vice President JD Vance described as “some progress,” particularly on Washington’s demands regarding Iran’s nuclear program.

In an interview with Fox News, Vance said Iranian negotiators had moved closer to U.S. positions on the removal of nuclear material and mechanisms to prevent future uranium enrichment, but were unable to finalize a deal, suggesting decisions may require approval from authorities in Tehran.

“There really is, I think, a grand deal to be had here,” Vance said, adding that the next step rests with Iran.The White House did not confirm whether preparations for a second round are underway. Press Secretary Karoline Leavitt reiterated that U.S. negotiating positions remain unchanged and pointed to increased pressure on Iran following the implementation of a U.S. naval blockade.

Multiple sources familiar with the discussions said both sides are considering further in-person talks aimed at reaching an agreement before the ceasefire expires next week. While Islamabad remains a leading candidate to host the meeting, other locations such as Geneva are also under consideration, with timing still undecided but potentially within days.

A diplomat involved in mediation efforts said there is growing alignment on holding another round, though details on the level of representation and agenda remain unresolved.U.S. President Donald Trump said earlier that Iran had reached out seeking a deal, underscoring continued engagement between the two sides even as tensions persist.

In an interview published Monday, Trump said the United States was in talks with Qalibaf, a former Revolutionary Guard commander. Qalibaf denied the assertion in a statement, saying Washington was “promoting desires as news while threatening our nation at the same time.

Iran’s Foreign Ministry also dismissed the claim. Spokesperson Esmail Baghaei said no negotiations had taken place, though he confirmed that intermediaries had conveyed proposals to Tehran.

Baghaei said Iran would not overlook what he described as past breaches of diplomacy, referring to indirect talks in 2025 and early 2026 that were followed by military action involving the United States and Israel.

War pressure shapes diplomacy claimsThe exchange comes as Trump has increased pressure on Tehran to reach an agreement to end the ongoing conflict, now in its fifth week following joint U.S.-Israeli strikes launched in late February.

Trump warned that failure to reach a deal “shortly” could result in widespread destruction of Iran’s energy infrastructure and critical facilities, including desalination plants.

Qalibaf’s role under scrutinyQalibaf, long viewed as a pragmatic conservative within Iran’s political system, has previously been mentioned as a potential interlocutor for Western governments.

However, questions remain about his authority within Iran’s complex power structure following the death of Supreme Leader Ali Khamenei in a February airstrike.His successor, Mojtaba Khamenei, is believed to maintain ties with Qalibaf, though competing centers of power within Iran’s leadership continue to shape decision-making.

Analysts say references to Qalibaf as a negotiating channel may reflect both external pressure tactics and internal political maneuvering, as Tehran navigates wartime conditions and diplomatic isolation.

Witkoff, speaking during a cabinet meeting, confirmed for the first time that the United States had passed the proposal via Pakistan, which is facilitating indirect communication between the two sides.

He said the effort sought to present Iran with what he described as a critical juncture, warning that failure to engage could lead to further escalation.

Germany’s foreign minister Johann Wadephul said the United States and Iran had already held indirect contacts and were preparing for a potential face-to-face meeting. He told Deutschlandfunk radio that such a meeting could take place “very soon” in Pakistan, though no official date was disclosed.

Pakistan’s role as a conduit underscores the absence of direct diplomatic ties between Washington and Tehran, with both sides relying on intermediaries to exchange proposals amid heightened regional tensions.

lAccording to the details outlined by Witkoff, the U.S. proposal includes stringent conditions on Iran’s nuclear activities. These include a prohibition on weaponization, dismantling of the Fordow nuclear facility, cessation of uranium enrichment, a ban on stockpiling nuclear material, and the transfer of enriched uranium to the United States.

Iranian authorities are currently reviewing the proposal, though no formal response has been announced.

The diplomatic push comes against the backdrop of an ongoing Middle East conflict that has drawn in multiple regional actors and intensified scrutiny of Iran’s military and nuclear posture. U.S. officials have framed the proposal as part of a broader effort to reduce hostilities and prevent further destabilization.

Witkoff said the outcome would depend on whether Tehran views the current moment as an opportunity to shift course, adding that discussions remain at a preliminary stage.
