The exercises are usually conducted in March and April, but in December South Korean President Moon Jae-In told NBC News his country was pushing the U.S. to postpone the exercises until after the Winter Olympics and Paralympics in PyeongChang, which end March 18, as an olive branch to North Korea.
North Korea has previously condemned the annual exercise and the large-scale mobilization of troops as provocative.
A spokesperson for the Pentagon would not confirm the dates of the exercises. "Additional information will be released after the Paralympics," Pentagon spokesperson Lt. Col. Chris Logan said.
North Korea has repeatedly censured the US and South Korea for holding military exercises and described the large-scale mobilization of troops as provocative.
This comes after Seoul announced the two Koreas would hold a summit in the Demilitarized Zone in April and that the North's leader Kim Jong-un was willing to stop provocative missile and nuclear tests.
Tensions have been high between Washington and Pyongyang over North Korea’s missile and nuclear programs.
Washington claims it prefers a diplomatic solution to the crisis, but it has repeatedly threatened Pyongyang with military action.
