Iran: The Latest – April 14, 2026

US and China on maritime 'collision course' as first ships try to pass Trump's blockade

Podcast Host: Roland Oliphant
Main Guests: Tom Sharp (Former Royal Navy Commander), Allegra Mendelsohn (Asia Correspondent)
Length: Approx. 43 minutes

Episode Overview

This episode delves into the rapidly evolving crisis in the Strait of Hormuz, where the United States’ newly declared naval blockade of Iranian ports sets the stage for possible maritime conflict, particularly with China. With the fragile Iran-Israel-US ceasefire still holding—and intense diplomatic maneuvering in progress—attention centers on the challenges and consequences of enforcing the blockade, the risks of direct US-China confrontation at sea, and the wider Asian economic and geopolitical shockwaves.

Key Discussion Points & Insights

1. On-the-Ground Updates: The War and the Blockade

[01:52–06:43]

• Status of the Ceasefire & Blockade:
  The episode opens by noting this is the 46th day of war, 7th day of a two-week ceasefire, and the first full day of the US military blockade targeting Iranian ports. According to US Central Command, America intends to intercept any vessel moving to/from Iran.

• Shipping Movements:
  No ships have yet been interdicted, but three significant vessels passed the Strait: all with distant Iranian ties, notably the Chinese-owned Rich Starry, sanctioned by the US for prior dealings with Iran.

• Diplomatic Movements:
  Keir Starmer and Emmanuel Macron will co-host talks to reopen the Strait, amid dire global economic concerns over the closure. Pakistan is proposing further in-person negotiations.

• Stalled Nuclear Negotiations:
  The latest failed Islamabad talks illustrate the deep divide—the US demanded Iran halt enrichment for 20 years; Iran offered 5.

• Lebanon Update:
  Fighting continues. Notable: Israeli-Lebanese direct talks in Washington—the first since 1993—and Italy suspending a military agreement with Israel.

2. Naval Blockades Demystified – Expert Analysis with Tom Sharp

[06:43–23:43]

How to Impose a Maritime Blockade?

• "I'm troubled by this to an extent, and it gets more complex when you put a blockade on top of an existing blockade." – Tom Sharp [07:22]

  • Tom Sharp explains the unprecedented dilemma: the US blockade now overlays Iran’s own closure of the Strait, creating legal and practical confusion.

• Freedom of Navigation Undermined:
  Initially, the US Navy had reassured allies by asserting freedom of navigation; the new blockade reverses this, raising Sharp’s concern over eroding long-standing maritime norms.

• Blockade Enforcement Realities:
  The logistics are daunting: limited US naval resources (maybe 8–10 destroyers), risky proximity to Iranian missiles, and hundreds of factors as international fuel and trade routes are tangled.

• Difficulties with ‘Flag of Convenience’ Ships:
  Many ships now fly Chinese (or Russian) flags, making legal boarding difficult and raising escalation risks.

  • "Are we really in the position of boarding Chinese flagged ships? I mean that's one hell of an escalation." – Tom Sharp [10:46]

• Practical Protocols for US Interdiction:
  Sharp outlines the stages:

  1. Situation Awareness: Gathering intelligence, tracking cargo/flag/registry (ignoring easily-faked AIS data).
  2. Choosing the Right Moment & Place: Should board as north as possible—riskier but more controlled.
  3. Approach & Boarding: Often by helicopter, possibly at sea ("fast rope" insertion if necessary).
  4. Post-boarding: Ship is steered to a holding area, e.g., Diego Garcia, for search/detention.
  • "At that point you declare your intention to board them... then you've really got two options: boat or helo insertion." – Tom Sharp [14:35]

• Escalation Risks – China or Russia Escorting Ships:
  If a Chinese navy vessel escorts a Chinese-flagged tanker, the US faces a massive escalation risk if it intervenes.

  • "A Chinese flag on the back offers you a great deal of protection. A Chinese escort alongside it – again... Are you going to board that? No, no you're not." – Tom Sharp [17:23]

• Real-World Precedents:
  Sharp references Venezuela’s blockade, describing a tanker (the Bella One) which avoided interdiction by signaling a potentially "opposed" boarding, triggering a prolonged mid-Atlantic pursuit.

• International Law ‘Gray Zone’:
  The risk is that if both the US and adversaries disregard maritime law, chaos and escalation become near-inevitable.

  • "If both sides just tear it up and go, this is now survival of the fittest... then you end up with complete chaos." – Tom Sharp [22:01]

3. China’s Role & Broader Asian Impact

Segment with Allegra Mendelsohn (Asia Correspondent) [24:36–42:44]

Energy Shockwaves in Asia

• Impact in the Region:
  • In Japan and Taiwan, effects are muted so far; the Philippines, however, declared a national energy emergency.
  • "Little things like at the airport...they made an announcement that...some of the lights were going to be switched off at 6pm, and obviously gas prices are astronomical." – Allegra Mendelsohn [25:35]

China’s Dilemma: Mediator, ENabler, or Escalator?

• Reluctant Diplomat:

  • China is acknowledged as having leaned on Iran to accept the ceasefire but remains publicly silent about its behind-the-scenes diplomacy.
  • "They want to acknowledge that they've really pushed for peace, but they don't want to get into the details as to, you know, what role they played in mediation." – Allegra Mendelsohn [28:25]
  • Reason: China rejects the principle of "interference" in other states’ affairs.

• Energy Dependence & Urgency:

  • China is a massive importer of Iranian oil (up to 1.6 million bpd during the war) and is keen for the region to stabilize to resume normal trade.

• Weapons Transfers Allegations:

  • US intelligence claims China is preparing to ship air defense systems (MANPADs) to Iran; China denies.
  • Regardless, stronger evidence China has supplied dual-use chemicals (sodium perchlorate for rocket fuel).
  • "It would be a pretty direct and explicit sign of support for Iran if China did follow through with this [anti-air missile shipment]." – Allegra Mendelsohn [31:22]

• Chinese Official Response:

  • Stern denials from Beijing: "China has never provided weapons to any party in the conflict... consistently fulfils its international obligations." [31:56]

Flashpoint: US-China Maritime Confrontation Risk

• Risk of Direct Showdown:
  Both sides face a potentially disastrous choice if US intercepts a Chinese-flagged vessel, or China openly challenges the blockade:

  • "There's kind of a game of chicken here, right?" – Roland Oliphant [36:20]
  • "I don't think either the US or China would like to go to war...there are economic consequences that could be imposed that would, I think, communicate that message pretty clearly." – Allegra Mendelsohn [37:12]

• Cautious Evasion Tactics:

  • Chinese tankers broadcast nationality more clearly to avoid accidental targeting.

• Trump’s likely response:

  • Tariffs rather than kinetic action; China likely to use its "ghost fleet" and creative sanctions avoidance.

Knock-on Effects for Taiwan Security

• US Resource Strain:

  • Significant US munitions diverted to the Iran war (e.g., 800+ JASSM missiles, >300 Tomahawks), with clear implications for a potential conflict over Taiwan.
    • "It would be pretty hard for it not to [impact US-Taiwan weapons deliveries]." – Allegra Mendelsohn [39:16]

• Chinese Calculus on Taiwan:

  • Despite PLA readiness deadlines, most experts believe a move against Taiwan depends on politics, not just military capacity.
  • US intelligence now thinks China prefers "other means" to assume control.
    • "If Xi Jinping decides he's going to invade Taiwan, it's going to be for reasons that are entirely to Xi Jinping." – Allegra Mendelsohn [41:17]

Memorable Quotes & Timestamps

• "Are we really in the position of boarding Chinese flagged ships outbound with commodities for them? I mean, that's one hell of an escalation."
  – Tom Sharp [10:46]

• "There are no rules anymore and that escalates to a shooting war every time. I mean it's almost impossible to imagine how it doesn't."
  – Tom Sharp [22:01]

• "They want to continue importing their crude oil as normal. They don't want to be dealing with a war and a blockade from either Iran or the US."
  – Allegra Mendelsohn [29:23]

• "This new blockade that the US has imposed is new, but I wouldn't put it past Beijing to find yet another way around it."
  – Allegra Mendelsohn [37:57]

• "I would say we're probably not on track for a war next year, fingers crossed."
  – Allegra Mendelsohn [41:20]
