The 2010 Korea F3 Superprix, due to be held on the weekend following the Macau Grand Prix later this month, has been cancelled.
The one-off event, held originally on the streets of Changwon between 1999 and 2003, was due to be revived this year by Macau organiser Barry Bland and held at the new Yongam circuit, which hosted the inaugural Korean F1 GP last month.
Bland was expecting a full 30-car entry for the race, with most teams and drivers treating Macau and Korea as a double-header, but Korean motorsport governing body KAVO has had to cancel the event due to Force Majeure.
Bland said: "KAVO have had to cancel the Korea F3 Superprix, due to Force Majeure. We understand this is due to a legal technicality with the circuit, which appears to have been brought about by some objectors.
"It should be a temporary problem, but that is all we know at the moment. This is hugely disruptive and disappointing, and it is obvious that the cancellation will bring many associated problems. Our priority is now to get everyone home quickly after the Macau event."
Bland said he expected the "government-backed" project to resolve its issues fairly quickly, certainly in time for the F3 Superprix to run in 2011.
"I do hope so," he added. "We have a contract for it and should be able to revive it next year. The track should lend itself to a very good F3 race."
