The United States primary strategy against China, in the event of war around Taiwan or nearby, is the same:

China's coast is mostly enclosed by the 'First Island Chain', which extends from Japan to Taiwan, through the Philippines and Borneo (look up a map and the situation will be very clear). Imagine strings of islands along the US coasts controlled by Chinese allies and with Chinese and allied forces training intensively there.

The American plan is to keep the Chinese navy trapped (or under assault) along its own coast by putting Marines (and Army soldiers too, I think) on the islands with anti-ship missiles.

The northern tip of the Philippines is as close to Taiwan as the Chinese mainland is; the US and Philippines are conducting an essentially endless series of military exercises and the US is placing some of its most advanced missiles there.
