The Northern Marianas' Commonwealth Ports Authority is in agreement with the US Federal Aviation Administration's position opposing the U.S. military's planned use of Saipan's International Airport for training exercises.
The exercises are in tandem with planned military activities on Tinian, linked to the military build-up in Guam.
The Authority wants the Saipan airport to be spared from any military operations because it is a commercial airport.
Last April, FAA officials cautioned against the military's use of the Saipan airport because of the disruption the activities may have on its commercial operation.
The Authority, however, said it is not against the military's use of the Tinian airport.
The U.S. military had emphasised that the use of CNMI airports is important to the islands' defence and security.
