The Aug. 18-28 exercise may trigger an angry reaction from North Korea, which calls the joint drills invasion rehearsals.

South Korea and the United States are set to commence their annual large-scale military exercise this month, a move designed to bolster readiness against escalating North Korean threats. The joint drills are, however, likely to provoke an angry response from Pyongyang, further straining diplomatic efforts.

Speaking at a joint press conference, officials downplayed concerns that South Korea’s new liberal President Lee Jae Myung is looking to scale back this year’s drills in an effort to open a door for dialogue with their northern neighbours.
