Vettel travelled to last weekend’s Mexican Grand Prix knowing he only had the slimmest of chances of overhauling Hamilton this season.
And his hopes were ended on Sunday as the Mercedes man came in fourth at the Autodromo Hermanos Rodriguez to create an unassailable lead at the top of the standings.
Sebastian Vettel admitted it was tough to take having also seen his title challenge ended in Mexico City last year.
But Arrivabene says Ferrari will not leave their driver hanging as they look to beat Mercedes to the constructors’ title.
“First of all, congratulations to [Hamilton],” Arrivabene told Sky Sport Italia.
“We do not give up. The constructors’ championship is still open, we have taken more points in that and do not give up until the end.”
Arrivabene added: “You have to be close to [Vettel] in down moments like this, we do not leave him alone.
“We must be strong and throw everything behind him, go forward and do not give up.
“We have proved we are together even if the others are saying otherwise. So let’s keep going.”
Arrivabene, who’s come in for flak this season as Mercedes chief Toto Wolff has been praised, was reluctant to discuss Ferrari’s pit lane rivals.
“I do not talk about the others,” Arrivabene said.
“We closed on them in the last two races, then I leave the judgement to you.
“Congratulations to Hamilton, but now let’s play for the constructors. It will be difficult but we will not give up.”
Ferrari are currently 55 points adrift of Mercedes in the World Constructors’ Championship standings.
Next up for Vettel and team-mate Kimi Raikkonen is next week’s Brazilian Grand Prix.
The final race of the season comes at Abu Dhabi’s Yas Marina Circuit on November 25.
