Professional Experience

Ms. Dong is a partner in the Beijing office and specializes in the areas of foreign direct investment, mergers and acquisitions, and telecom, internet, high-tech and data privacy and information law. She represents multinationals, foreign investment enterprises, and large Chinese state-owned and private companies. In her corporate and M&A practice, Ms. Dong guides inbound investors through all stages of operation in China, from market investigation to market entry and business expansion (including incorporating PRC entities, mergers and acquisitions, business permits and applications, corporate restructuring and compliance issues). Her clients include industry leaders in manufacturing, high-tech and internet and telecommunications services and education. By supporting clients in their operations in China, Ms. Dong has not only gained substantial experience in dealing with complex commercial transactions but also a deep understanding of the law and its implementation, government policies and the business environment, which enables her to assist clients to set up sensible strategies and explore practical approaches to doing business in China.

She also advises clients on all aspects of matters involving new technology and data, with a special emphasis on information privacy (consumers, employees, and patients), data security and breaches, and international data transfers. In these businesses, she has gained an understanding of new business models and technology, such as targeted advertising, internet payments, telematics, IoT and cloud computing, so as to help clients navigate China’s complex and sector-specific policy and regulatory landscape. Her clients include national and international information technology vendors, internet service providers, data brokers, retailers and distributors, and manufacturers of medical, industrial, and consumer products.

She also consults with JunHe lawyers and clients on eDiscovery strategy, data privacy and state secret law matters.
