MotoGP will return to the Czech Republic for the next five years after Brno signed a new contract with Dorna.
The Czech Republic held its first-ever race back in 1965 while the Brno circuit has been ever-present on the MotoGP calendar for more than two decades.
Despite record attendances over the past few seasons, there have been reports in recent years that organisers are facing financial problems with MotoGP commercial rights holder Dorna forced to bail out the race this year.
The track, though, secured its immediate future on Sunday by signing a new five-year contract.
The CEO of Dorna Sports, Carmelo Ezpeleta, said of the deal: "The Czech GP is one of the highlights of the championship as it's been on the calendar for 50 years and as we see this weekend again, it's a very popular event.
"We are very happy to reach an agreement with the Czech authorities that will ensure the future of the Grand Prix in the Czech Republic for at least the next five years."
Katerina Valachova, Czech ministry of Education, Youth and Sports, added: "We're proud to announce that Brno will host MotoGP again in 2016 and the four following years, thanks to the creation of a new public body involving the Meridional Moravia Government and the City of Brno."
