The U.S. Congress has given the green light to the sale of four spy drones to South Korea.
The approval has been a long time coming as Seoul requested the Global Hawk drones eight years ago.
South Korea's Defense Acquisition Program Administration said Thursday that it received a letter of approval from the Pentagon in mid-April.
It is not a done deal, however, as Seoul and U.S. manufacturer Northrop Grumman are far apart on the price.
The South Korean government reportedly offered some 435 million U.S. dollars for the drones but the U.S. values them at 1.2 billion dollars.
South Korea might now start accepting bids from other drone makers such as Boeing and AeroVironment.
Seoul wants to use the drones to gather intelligence on North Korea once it takes over wartime operational control from the U.S. in 2015.
