"To ensure the safety of ITB China’s exhibitors and visitors, the organisers decided to postpone ITB China 2020, and in a responsible way allow all participants to make necessary arrangements in a timely manner. The ITB China organisers will continue to monitor the situation closely and provide further updates based on official assessments of the overall risk situation."
