He also advises on technology transfer regulations, joint venture IP contribution structures, and licensing arrangements that comply with Chinese regulatory requirements.

Ziyong Xiao structures each engagement around clear scope, document checklists, and realistic timelines so foreign clients and overseas counsel can coordinate with the local Chinese process without language barriers. Where matters involve Trade Secrets, the focus is on preserving evidence early, mapping the competent authority, and choosing between negotiation, mediation, arbitration, or litigation based on cost and enforceability.
