With relations between China and the U.S. continuing to deteriorate, a new video released by China's air force may be another source of concern.
The highly-produced piece released on a social media platform shows Chinese bomber aircraft, capable of carrying nuclear weapons, launching a simulated attack on what appears to be an America air base in Guam.
The Pacific island and U.S. territory is home to major military facilities, and its air base would be a likely target for any conflict in the Asia-Pacific region.
The Chinese video - named "The god of war H-6K goes on the attack!" - shows H-6 bombers taking off from a desert base.
A pilot eventually presses a button which sends a missile towards an unidentified runway.
When the missile homes in - a satellite image is shown that looks exactly like the layout of Andersen Air Force Base in Guam.
The timing of the video's release coincided with China performing a second day of drills near Taiwan to express anger at the visit of a senior official from the U.S. state department.
Neither China or the U.S. immediately responded to requests for comment on the video.
