The Asia Pacific Regional Forum of the International Bar Association created a guidebook on business regulations in the APAC region. It is jointly composed by a consortium of law firms and covers the main topics for eleven jurisdictions in the region. As from page 104, a whole section is dedicated to Hong Kong. Thirteen chapters are available, each of them tackling a different segment of regulation in this international business centre.
