North Korea has removed two medium-range missiles from a launch site on the east coast, indicating a lowering of tension on the peninsula, a US official said.
Pyongyang reportedly made preparations for a missile launch last month.
It had threatened attacks on specific targets on South Korea, Japan and US bases in the region.
The threats followed tough new UN sanctions imposed on North Korea in March after its third nuclear test.
Pyongyang has also been angered by wide-ranging annual US-South Korea military drills, which were completed a week ago.
The US flew nuclear-capable B2 and B52 bombers over the South as part of the drill, and deployed warships with missile defence systems to the region.
A new series of joint anti-submarine drills began on Sunday and will last until Friday, South Korea's Yonhap news agency reports.
