Called Ulchi Freedom Guardian, the joint drills will take place from August 21 to August 31 and involve computer simulations created to prepare for the unthinkable: war with nuclear-capable North Korea.
"There is no intent at all to heighten military tension on the Korean peninsula as these drills are held annually and are of a defensive nature", Moon told Cabinet ministers, while warning Pyongyang not to engage in provocations.

Merciless retaliation: N Korea issues fiery threats over US-South Korea drills
North Korea typically responds to South Korea-U.S. military exercises with weapons tests and a string of belligerent rhetoric. President Donald Trump warned North Korea this month it would face " fire and fury " if it threatens the United States.
President Kim Jong Un's regime slammed the annual drills while also vowing vowing that Guam, Hawaii and the USA mainland could not escape a "merciless strike", CNN reported Sunday. North Korea, for its part, threatened to launch missiles toward the American territory of Guam before its leader Kim Jong Un backed off saying he would first watch how Washington acts before going ahead with the missile launch plans.
North Korea views such exercises as preparations for invasion and has fired missiles and taken other actions to coincide with the military drills in the past. In 2015, North and South Korea exchanged artillery fire at the same time as the Ulchi Freedom Guardian drills after the South began blasting propaganda on loudspeakers across the border.
Some 40,000 South Korean and USA troops are to participate on land, sea and air in the exercises called Ulchi-Freedom Guardian.
In a month in which President Trump and the North Korean regime have already traded nuclear threats, analysts predict the routine war games could be tenser than ever.

But Kazianis said he would not be surprised to see North Korea carry out its sixth nuclear test or another intercontinental ballistic missile (ICBM) test during this year's exercise.
"Kim Jong Un might make the logical decision that it's probably bad to test during a military exercise", Kazianis said.
