Yes China has historical claims. Doesn’t Israel also have historical claim to all of Palestine? Does it have the right to take it by force.
Some of those islands are over 1000km away from Chinese mainland and less than 100km from Philippine coast.
It’s so close to the PH that it’s part of their EEZ for which they have sovereign rights as stated by the UN.
Laws have changed since the Song dynasty.
EEZ applies to territory not already owned by someone else.
UN consider status of Palestine and Israel as unsolved. Which effectively does allow both sides to fight over it.
Then you can speculate a lot into the fact that there's no real claims for a colonizing khazarian dominated state there, other than ones based on illegal British invasion. But as far as UN is concerned, both sides can fight over the area because it's in dispute, which is why many are pumping aid into Palestine and Lebanon to help resist Israel, while other countries are (keyword)
trying to condemn Israeli brutality. If Israeli "claim"
was recognized by UN, an attack on Palestine would be a genocide against its own people (as recognized by the UN),
there would be trying for condemnation, they would simply be immediately condemned.
Meanwhile in SCS, Philippines is moving into territory that are internationally legally speaking, Chinese. But China recognises ambiguity in unpopulated territories, which is why instead of facing gunfire and crowd control weapons like Indians marching over the border, Philippines is only facing marine policing units, and China is maintaining a dialogue with Philippines to solve the issues through negotiation.
