GUAM (REUTERS) - The commander of Andersen Air Force Base on the US Pacific island of Guam on Friday (Sept 25) said a Chinese air force video that seemed to show a simulated attack on his facility was "propaganda" designed to coerce and antagonise.

The video showed nuclear-capable H-6 bombers striking what appears to be Anderson, though it did not directly mention the base name, as regional tensions rise and the US carries out a major biennial drill near Guam.

"I'm always concerned about our ability to protect our service members and their families," Brig-Gen Jeremy T. Sloane, Andersen's commander, told reporters on a conference call about the ongoing Valiant Shield exercises.

"The video itself - they know the timing of the exercise," he added.

"It's a propaganda video... although we're always concerned about the protection of the island and the protection of our people, the video itself is just purely propaganda designed to coerce and antagonise us."

The Chinese government has not commented on the video, which lifted taken some scenes from Hollywood movies like Transformers: Revenge of the Fallen, to the amusement of posters on Chinese social media.

It was released on Sept 19 on the Chinese air force's Weibo account, in the midst of the Sept 14-25 Valiant Shield drill.

Sloane said Valiant Shield continued as scheduled.

"The exercise itself is going to go on as planned because it's designed to make sure that we're trained and ready to conduct ourselves across a variety of operations in the Indo-Pacific and to support our allies and partners."

Guam is home to major US military facilities, including the air base, which would be key to responding to any conflict in the Asia-Pacific region.

The video also came as China carried out a second day of drills near Chinese-claimed Taiwan, to express anger at the visit of a senior US State Department official to Taipei.

The H-6 has been involved in multiple Chinese flights around and near Taiwan, according to Taiwan's air force, including those last week.
