Things are heating up again in the waters south of the PRC. First there was a strange incident in which two people drowned. The PRC says it was a fishing boat that had been in the waters around Kinmen, an island belonging to Taiwan/the ROC, but very close to the PRC. However, a fishing boat can 1) not outrun a coastguard boat and 2) does not capsize easily, unless Godzilla drags them down. Another article mentioned a speedboat, which is much more likely, as it is sufficiently fast and unstable for the described incident. So very likely people from the PRC were speeding into waters they didn't belong to and then ran - and did so in a way that made their boat capsize and got two people drowned.

However, the PRC is now very "concerned about the safety of Chinese fishermen", which led to them sending their own coastguard into waters around Kinmen and stopping a tourist boat there, checking the papers of every person on board. Basically they officially entered waters belonging to Taiwan and claimed authority there. But it's not just about #Taiwan.

There is still the problem with the second Thomas Shoal. The PRC escalated their bullying of Philippine supply boats heading to a grounded ship in the Second Thomas Shoal. This is in the Exclusive Economic Zone of the #Philippines, less than 200km from their coast, while being 1000km from the PRC coast. (EEZ is defined as everything within 200nm from the coast.) The PRC called the supply run an "intrusion into their territory" and this time, coast guard ships from both sides bumped into each other. Please observe that only the PH sailors put out fenders, while the PRC sailors were busy filming.

That's the current level of escalation, so use your imagination for the next one.
