Olena helps clients anticipate, navigate and shape the trade and regulatory environment affecting their global operations. Her practice covers the full spectrum of international trade issues, including anti-dumping, anti-subsidy and safeguard investigations, sanctions and export controls compliance, customs audits and disputes, optimization of customs procedures, HS classification and rules of origin analysis, the development of supply chain traceability systems, and legal support for entering new foreign markets. She also conducts trade and customs due diligence in cross-border transactions and supports both Ukrainian and international companies during regulatory inspections and enforcement actions.

She regularly defends investors in disputes concerning unlawful trade barriers, advises on trade-related aspects of investment projects, and develops strategic legal solutions that enable clients to mitigate sanctions risks, improve compliance, and achieve long-term competitiveness in global markets.

Before joining Ilyashev & Partners, Olena held senior positions in several Ukrainian governmental institutions, where she was responsible for aligning national legislation with EU law, developing Ukraine’s trade policy, conducting investigations into unfair trading practices, and representing the state in international negotiations. She served on Ukraine’s negotiating teams for the EU-Ukraine Association Agreement and free trade agreements with Canada, Turkey, Serbia and other jurisdictions, directly contributing to the country’s international economic integration.
