China does not recognize the international tribunal’s ruling.
The international tribunal did not have the standing to make the ruling that it did. China’s claim to the ECS predates the UN and the international court, the UN (lead by the USA) stole control over the sea and retroactively legalized their theft while China was fighting a civil war.
For the record, Taiwan claims precisely the same thing. But they’re a US-backed puppet regime so they can’t move against the US the way that the PRC can.
Cry harder western shill.
