China claim the straight and, under maritime law, if that’s accepted then it’s theirs. So, British etc. ships sail through it saying “what a lovely straight of water. I’m going to sail through here, as no one owns it.” If China doesn’t react, they have relinquished their claim to the straight. So, they have to follow up with “hey you, get off my lawn!” Every so often, the dance is repeated.
Its just a dance both sides are doing.

Nothing to worry about.
