Lee, Tsai & Partners

In July 2001, we worked with attorneys at Shanghai to create a legal team to assist multinational companies and Taiwanese companies in their inbound investments into China. Continuing our steadfast commitment to our clients and in response to their pressing need for legal expertise on the increasingly close economic relationship between the PRC and Taiwan, we again worked with attorneys at Beijing to create a new legal team in July 2010.  The joint work is aiming at the goal of assisting multinational companies in developing their business in the more integrated economy of the Greater China region and assisting local PRC companies in their outbound investments with a specific focus on investments into Taiwan.  The Lee Tsai Group's seamless operation between offices allows our clients full access to our entire professional team, regardless of location.
