International Judo Federation (IJF) President Marius Vizer has claimed the organisation is hopeful the Tunis Grand Prix will be reinstated but admitted the Tunisian Government has not yet provided the required guarantees on the participation of Israeli athletes.
Vizer said discussions were ongoing between the IJF and the Government in the African nation following the decision to suspend the event last year.
The IJF is seeking assurances that Israeli athletes will be able to compete in the country without discrimination before the Tunis Grand Prix can return to the international competition calendar.
The Abu Dhabi Grand Slam was also suspended but was restored in September after restrictions on Israeli athletes were lifted by officials in the United Arab Emirates.
Israel participated under its own flag at last year's Abu Dhabi Grand Slam, which the IJF described as a "watershed moment".
There have not been any updates regarding the Tunis Grand Prix since it was axed from the calendar.
In response to a question from insidethegames on Twitter, Vizer said the IJF was "continuing the discussion with the Tunisian side" and was not giving up hope that the event would eventually be reinstated.
"As soon as they can follow our request, the event will be reinstated," he added.
We are continuing the discussion with the Tunisian side. We don't give up. As soon as they can follow our request, the event will be reinstated #AskVizer— Marius Vizer (@MariusVizer) February 10, 2019
The decision to suspend both events followed several flashpoints involving Israel in judo and came amid a wider sporting aim to clamp down on athletes from a certain nation being barred from an event in another country for political reasons.
The suspension of the Tunis Grand Prix was made at the time the country was bidding for the 2022 Youth Olympics.
The International Olympic Committee initially blocked the bid from Tunisia for the event, eventually awarded to Senegal, due to its treatment of Israeli athletes before it was reinstated after the Government said it had ended restrictions on the country.
Malaysia was recently stripped of this year's World Para Swimming Championships after the nation refused to let Israel compete.
Israel hosted an IJF Grand Prix last month in the calendar slot usually filled by the Tunis Grand Prix.
The event in Tel Aviv was the first IJF World Tour competition held in Israel.
