Overview
Helen represents financial institutions, fintech companies, and multinational corporations in cross-border litigation and regulatory matters.
Helen Jiang’s practice centers on the intersection of banking, financial services, and international law, areas where procedural complexity, regulatory exposure, and business stakes converge.
On the litigation side, Helen handles shareholder derivative actions, disputes involving notes, guaranties, and structured financial instruments, and cross-border enforcement matters. She brings a particular depth to cases that require navigating both U.S. court proceedings and foreign legal systems, drawing on her training and practice experience across three jurisdictions.
Helen also advises financial institutions on risk management and remediation strategies when regulatory issues arise. For fintech companies and other financial service providers, she counsels on compliance with federal and state requirements governing reporting obligations, payment systems, and fund transfers, helping clients build and refine compliance frameworks before problems escalate to enforcement.
Her background spans the full arc of international dispute resolution. Early in her career, Helen practiced in the international arbitration group of a Legal 500 firm in London, served at the World Bank's International Centre for Settlement of Investment Disputes (ICSID), and was a scholar at the Hong Kong International Arbitration Centre (HKIAC). That foundation informs her work with American and Chinese companies navigating contract and business tort disputes across borders.
As a bilingual attorney fluent in English and Mandarin, Helen works directly with clients and counterparties in both languages, an advantage in matters where language and cultural context shape negotiation, fact development, and strategy.
