China criticises UK warship HMS Spey sailing in Taiwan Strait

But, of course, when China sails two aircraft carriers through Japanese EEZ, it's Japan's fault for flying their surveillance too close by.

If China wants to keep escalating skirmishes and expanding ownership claims then it forces world powers to travel via the strait to demonstrate that it's still a regular legal channel of international naval transit, owned by no-one. The channel is 130kms wide at its most narrow section ffs.. the closest passing ships come to land is ~65kms. That's a pretty large buffer.

China just sailed a fleet of their own warships around Australia three months back, crossing into Australian territorial waters a number of times and even conducting live firing tests in the waters between Australia and NZ. None of which was done with permission, or necessary to be done near Australia or NZ. There are enormous uninhabited sections of ocean that would have been less travel (and cost) for them to reach - its just done to flex muscle and could just as easily be framed as "intentional provocation" and "undermining peace and stability". So its 'rules for thee, not for me'.

Meanwhile Chinese Navy keeps ramming fishing boats in international waters

Its just a dance both sides are doing.

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.

Nothing to worry about.

Cry about it, Xinnie.

It would be darkly funny if China made all the British sailors buy opium.
