chief executive Bernie Ecclestone recently checked on construction progress of the Yeongam circuit and dismissed rumours it will not be finished on time.
But political tensions between South Korea and the rogue North have since ramped up, after the South blamed the North for the sinking of a naval vessel and the North retaliated by threatening all-out war.
“If there is (war), we won’t be there obviously,” Ecclestone told reporters in Turkey.
The latest development on Wednesday was a news conference given by the North Korean ambassador to the UN, threatening military action if the UN condemns the sinking.
“Our people and army will smash our aggressors with merciless counter reaction if they dare to provoke us despite our repeated demands and warnings,” said ambassador Sin Son Ho.
Sources recently indicated that the tension is slowing down construction of the 5.62 kilometre track, while teams are currently reluctant to charter equipment to Korea or book airline seats or hotel rooms.
But in a media statement, the race promoter Korea Auto Valley Operation (KAVO) dismissed the speculation.
“We are extremely pleased with the progress of the circuit, facilities, and preparations for the Grand Prix,” said chief executive Yung Cho Chung.
“Construction is on schedule for completion this summer, and we have encountered no obstacles whatsoever, either logistical or political,” he added.
