What's missing is~ what are the coordinates? This is nothing but an attempt to harrass southeast asian vessels~
Without a clear and definitive boundaries, how will the regulation be enforced? It will most likely end up being bullying weaker southeast asian vessels just like what happen in Natuna Sea last year. With this uncertain boundaries The Chinese could harrass foreign vessel in name of law enforcement and gradually enchroacing other countries territories.
Espcially at Natuna Sea, the Chinese cleverly leaves out any definitive dash there. A lot of chinese vessels have been spotted near natuna islands, only several vessels are detained by Indonesian as Chinese maritime vessels No. 311 step in and threatend to shoot inferior Indonesian boats despite it is clearly within Indonesian declared EEZ (by precisely coordinated bilateral agreement with Vietnam and Malaysia).
