The 21st round of TiSA negotiations took place from 2 to 10 November 2016. The agreement, which aims to liberalise trade in services, involves 23 World Trade Organisation (WTO) members who jointly account for 70% of world trade in services.

The last round was chaired by the EU. The negotiating partners attempted to advance the most controversial issues which could not be resolved thus far. During this round the revised offers, as well as technical discussions, were addressed.

Concerning maritime transport, the round looked at the articles related to the movement of empty containers, the prohibition of cargo sharing agreements, the access to ports and to port services, as well as port fees and charges.
