The inquest into the killing of 38 holidaymakers - all of whom were Tui customers and 30 of whom were British - is due to begin on January 16 next year.
It will attempt to determine how much the UK government and travel firms knew about the risk of an attack on tourists holidaying in the North African destination.
Speaking to TTG at a Tunisian National Tourist Office media event in London, Sami Tounsi, trade manager at the Tunisian National Tourist Office said if Tui was deemed liable for not issuing its customers with enough security warning prior to the 2015 terror attack, it could make operators reluctant to return to Tunisia and nearby countries.
