A North Korean foreign ministry official said the military drills and "bellicose remarks" by USA officials "cannot be interpreted in any other way but as a warning to us to be prepared for a war on the Korean peninsula".
Around 12,000 US service members, including from the Marines and Navy, will join South Korean troops.
The drills come a week after North Korea said it had tested its most advanced intercontinental ballistic missile capable of reaching the United States, as part of a weapons program that it has conducted in defiance of global sanctions and condemnation.
