The US geopolitical objective is to destroy China’s power. This is being pursued variously. China’s economy depends on Asian sea traffic. The US military strategy is to sever those sea lanes. Thereby China’s economy is imperilled.

However, as the US itself has claimed (from Obama on) it lacks the resources to achieve its objective. It says it must rely on allies’ support.

Unsaid by US planners is that those same sea lanes upon which China depends are critical also for Japan and Australia. Any pedant can see that the natural allies here are China, Japan and Australia.
