South Korea has spent around 10.2 billion won, or some 8.5 million dollars, in combined exercises with the U.S. in the past 4 years.
The figure is included in a report submitted to the National Assembly by the defense ministry and the Joint Chiefs of Staff, on the drills conducted since 2016 up to this March.
Around 1.8 million dollars went to the 2016 Key Resolve exercise, and 1.7-5 million to the Ulchi Freedom Guardian drills that same year.
The recent Dongmaeng drills held in March cost the nation some 9-hundred-60 thousand dollars.
Based on these numbers, some military officials refuted U.S. President Donald Trump's claims that its allies are “free-riding” America's security commitments.
Other analysts pointed out, as the drills following the Pyeongyang-Washington summit were smaller in scale and did not involve strategic U.S. weapons, the cost should go down significantly.
