The race will, however, remain as part of the previously released 2006 Champ Car schedule.
The series says that The Racing Korea (TRK) - the local promoter - brought about this decision through a lack of operational preparation and failure to comply with contract requirements.
Champ Car nevertheless claims it has "a strong relationship with the Mayor of Ansan" and is "quite confident in the city’s ability to move forward with the race in 2006".
“We made every effort to avoid this deferment and have been working very closely with the promoter as well as Mayor Song Jin Seop and the City of Ansan in finding a solution that would allow us to run this event as scheduled,” said Champ Car executive vice-president of development, governmental affairs and planning Joe Chrnelich.
“We have a lot of equity in this market and there are many positive indicators, including interest from major title sponsors, a supportive Mayor and a great circuit that is near completion.
"This demonstrates to us that we can have successful events in Ansan provided we show patience and continued confidence in the Korean marketplace, and we will.”
