I also note that they think they South China Sea all the way down to the Spratly Islands belongs to them, and they are attacking Filipino boats (mostly with water cannons) that venture into that area, even though China lost all of their appeals in the international courts regarding those claims (i.e. they are Filipino islands, not Chinese.

Yes, Spratlys are in the Filipino EEC. They do ram a boat periodically, last one was a supply ship to the grounded boat where Filipino sailors live on an island. China was making overtures to split the oil revenue from the EEC, but that approach has stalled I think. Duterte started reversing his friendship with China and we did get permission for bases. Bong Bong and Sarah Duterte seem friendly.

China seems to not bother Malaysia, but Indonesia has sunk a couple of Chinese fishing boats. Vietnam is not friendly bordering to hostile with China. S Korea is not friendly with China. Laos seems friendly, or at least in debt.

Singapore has strong ties to China, but has not supported the 9 dash line and Terrex vehicles used in War Games with Taiwan were seized in hong Kong port. So ?
