Alexander Yean

Alexander Yean

Call: 2022 (England and Wales); 2025 (DIFC)

Languages: Chinese (fluent)

Alex has a busy practice spanning Chambers’ core areas of shipping, commercial arbitration/litigation, and public international law (including investor-State arbitration). He has been involved in dozens of arbitrations under a variety of rules, including LMAA, SCMA, HKMAG, GAFTA, LCIA, ICC, SIAC, UNCITRAL, and ICSID, as well as proceedings in the High Court. He is regularly instructed as sole counsel (often against more senior opponents), but equally enjoys working as part of a team, especially co-counselling together with law firms.

Alex is swiftly developing a specialism in relation to sanctions, which cuts across all of his practice areas. He is instructed in some of the most significant and high-profile ongoing international law disputes with a sanctions element, including ABH Holdings S.A. v. Ukraine (ICSID Case No. ARB/24/1), which concerns the nationalisation of a leading Ukrainian bank on the basis that some of its ultimate beneficiaries were subject to foreign sanctions, and Fridman v. Luxembourg (PCA Case No. 2025-42), which concerns the (un)lawfulness of EU sanctions imposed on the Claimant as a matter of international law. In relation to English law-governed disputes, Alex is acting in, among others, a US$800 million SIAC arbitration which turns on (among other issues) whether sanctions imposed against the buyer constitute a force majeure event, as well as several LMAA arbitrations concerning vessels alleged or suspected to be part of the so-called “shadow fleet”.

Other recent and ongoing instructions, which illustrate Alex’s varied caseload, include:

  • A v. B (Commercial mediation): Acted for the Claimants against a KC in a 1-day mediation of a 8-figure claim that involved a novel point of law and was scheduled for a 3-week High Court trial; dispute amicably settled.
  • Investor v. State (UNCITRAL): Acting for the Claimant in a multi-billion dollar claim for alleged expropriation of investments in the real estate sector; cross-examined multiple fact witnesses (including State officials) and the Respondent’s legal expert at the hearing.
  • The Manta Penyez [2025] EWHC 353 (Comm): Acted as lead counsel in obtaining final (and before that, interim: [2024] EWHC 3109 (Comm)) anti-suit injunctions in the High Court to restrain foreign proceedings that had reached the apex court in Djibouti and the appellate courts in Yemen; advocacy described by Mrs. Justice (now Lady Justice) Cockerill as “excellent and careful”.
  • A v. B (LMAA): Acted for the respondent in a US$10 million shipbuilding arbitration; conducted 5-day hearing unled against a counsel team led by the head of chambers of another shipping chambers. Secured the full dismissal of all claims against the respondent.
  • A v. B (LMAA): Acting as lead counsel in an arbitration arising out of breaches of a ship sale agreement that raises highly complex and novel issues of law, before a tribunal comprised of former High Court judges.

Prior to joining Chambers, Alex studied law at the University of Oxford, where he came top of his year overall. He maintains a strong academic interest in law and his contributions have been published in leading academic journals. He regularly gives guest lectures on international arbitration and public international law at leading law faculties around the world, including Columbia Law School and the Peking University School of Transnational Law.

Alex is fluent in Mandarin Chinese, having grown up in Singapore, and is particularly valued for his experience in cross-examining Chinese-speaking witnesses (without the aid of interpretation) in front of English-language tribunals. He frequently travels to Asia for hearings, and maintains a keen interest in the region.
